AELicice dealerEDITORIALLY SPEAKING

10 YEARS OF COLORDecember 17th 1963 was no different than any other date,

to most people, but to the Television Industry it marked theten year anniversary of the beginning of color Television.When you stop to think that commercial Television actuallybegan in 1946 it doesn't seem possible that color has ac-tually been with us for over half of this period.

After ten years, color is really only coming into its owntoday. Why has it been so long in coming? What has beensome of the direct results? Where do we go from here?

The service industry may have been responsible for theprincipal delay in the acceptance of color. Actually, theservice dealer himself falls into one of three categories. Onegroup of dealers awaited any opportunity to hear about, see.operate, and service a color receiver. The majority of theseby and large have enjoyed color programming since 1954.Since they watched color they were in an excellent positionto judge whether customers receivers were operating prop-erly, and they could speak from experience when the new-est proud owner, having become a color expert overnight,became confused over transmission variations and color qua-lity. Also, because of this approach to the new color receiv-ers, this group purchased the very latest in color test equip-ment and rejected the gimmick type of instruments thatbegan to flood the market.

A second group followed an opposite course. Some ofthese dealers shuddered and closed their eyes and hopedthat color would die a natural death. In a way it did fadelike a sleeping giant until the last few years.

The third group. and very likely the largest number ofdealers simply ignored the problem until they were askedto perform service. They took no part in the discussion, at-tended few meetings where convergence and setup weredemonstrated, and in many cases never actually make asetup, or even operated a color receiver.

The members of this group may find it difficult to com-pete with the men who have serviced color for years, becausepeople with experience and interest can deliver more per-formance and enjoyment to the customer.

I am not placing the blame on the service industry be-cause half of the problem came from the retailer as well.This dealer was faced with a high ticketed product with asmall margin of profit. How much easier was it to sell downcolor in place of a high ticketed long profit black andwhite set? The stock answers to customer questions usuallyfell in two or three categories. First was the "wait until itis perfected." How about the "we usually send along amidget service man with each set." Each of these had thereeffect on the customer.

The service dealer . . . then the product dealer . . . andthen. of course, the network battles to present or suppresscolor certainly added to the confusion.

These are the basic reasons why color was a long timecoming. Its effect will add new jobs, upgrade pay scalesand, because of the requirements of more knowledge, willtend to raise the status of the service group.

The future, of course, is up to the individual servicedealer. Estimates now indicate that 1963 will be the firstyear that color sales will reach the billion dollar mark. Al-

ready many manufacturers are estimating that color in1964 will reach 1.7 million sets. This is close to 20% of theentire Television Production for 1964 and is only the be-ginning.

If we, the members of the service profession, use ourskill and energies to make entertainment more enjoyableand important to our customers we should see our futureexpand and improve in a direct ratio to our efforts. Sincecolor can bring so much more into the home. it wiN beworth more to all who have it.

In keeping with this trend to more and more color MESDwill continue to provide articles that relate directly to colorservicing. Ten years of color begins in this issue. We wouldappreciate any comments you might like to make.

CABLE TV GETS STRONG OPPOSITIONIn a recent issue of MESD we ran an article about the

formation of a new organization called TAME, Inc. Thisassociation is composed of major antenna manufacturersthroughout the United States and was formed to "fightagainst the indiscriminate franchising of community an-tenna systems that seem to be cropping up in different partsof the country."

In certain States, such as Georgia, a full scale attack onthe problem is shaping up. TAME officials are doing every-thing possible to inform the government bodies of the needfor certain regulations. Another part of this attack will bespearheaded by newspapers, radio and television mediumsto inform the public about CATV. Special dealer meetingsare also being held to obtain the full backing of our indus-try in this fight.

"TAME's prime purpose in engaging in these campaignswill be to bring all the facts to light in the interest of theviewing public, so that a clear and authoritative choice be-tween being a life-long subscriber with CATV, and theowner of a paid -up antenna system can be made." Thisstatement was taken from a recent news release that wassent to us and is pretty indicative of what is involved.

As for the Service Dealer, his problem with CATV is alittle different. The fight, of course, is the same but thechoice is being a life-long subscriber of television servicewith CATV or the independent service dealer who is a vitalpart of every community in America.

In writing this report I kind of wonder just how faralong our Industry would be today if the major independ-ent manufacturer of parts would have taken the same standagainst captive service? A great deal of the captive servicebusiness includes "captive parts" doesn't it?

Anyway, our tip -of -the -hat to TAME and its members whohave the foresight to combat a problem in the antenna mar-ket. Every service dealer in the country should voice hisopinion to his customers when the question present, it -elf.

In making this recommendation, theBoard pointed out that the return of theused picture tube would be a hazard tothe health and welfare of the public andtherefore should be excluded from thisportion of the registration law.

After the formal action was taken itwas forwarded to the new chief of theDepartment for further action. The Ad-visory Board itself does not have thepower to make any changes but actsonly as an advisory committee to theDepartment.

The efforts and perseverance of someService Dealers through out the statethese past several years are being recog-nized more and more. The formation ofthe California State Electronics Associa-tion and the accomplishments this or-ganization has made in creating a moreprofessional attitude among service deal-ers is outstanding and to, it is the repre-sentative of the independent service deal-er in legislative action for the benefit ofall.

Now with a well founded and func-tioning organization I hope to see in thecoming year several important problemssolved. such as apprenticeship trainingin the electronics industry to developqualified Technicians and in doing so.protect the consuming public against in-competent and unethical Service Dealers.On the other hand I would like to seeService Dealers develop better businessprocedures for dealing with the consum-ing public, as to what constitute legiti-mate pricing policy for the services theyperform. This problem is compoundedin many shops because of the negligencein bookkeeping procedures used, in notshowing a break even point before aprofit can be realized.

A major problem as I observe the in-dustry is by not having a procedure de-veloped for properly qualified men whoenter this industry as to their Technicalqualification.s I believe with an operat-ing apprenticeship program within theElectronics industry it will he possible toamend the Electronic Repair DealerRegistration Law to include an articleon the qualification procedures. I hopethe Board of Directors of the CaliforniaState Electronics Association makes a

sincere study of this problem and willwork towards accomplishing this fea-ture.

HOW'S YOUR

c3E-X_Alk.3ECIT'"Mr"

With the growth and development ofmany local and national charity funds,problems have arisen for not only theservice dealer but all recipients of theplea for assistance. The legitimate chari-ty fund drive is a delicate and importantissue both morally and business wise.

These campaigns are often a two-waycompromise, benefiting not only thecharity but the reputation of your busi-ncs,. A major problem however is justwhich is the best charity to donate to,or is it wise not to allow partiality toany particular group, or should a lumpsum be given to one group in particular,or small amounts of money or help toa number of different organizations.There are many aspects that must belooked into and it appears that too manyindividuals are being caught unpreparedwhen such situations arise.

What is the best way to handle a re-quest for charity then? As point numberone it should be indicated that mostservice dealers operate within a givenarea, neighborhood, or community. Re-lations with the people in the generalbusiness district is of utmost importancein regards to your service and businessreputation. It would then obviously hewise to support the popular charity ofthe customer - the one that they areperhaps even working on. There reac-tion would naturally be that your verybest interest is with that of the rest ofthe community and that you are willingto cooperate with the large group ofcustomers that have preferable tenden-cies to one charitable fund. This is ofcourse easier said than done. It is notalways just as easy to recognize thatone particular fund that the communityis most sympathetic to. If any one hadthe time or the patience to delve intoa study of charitable tendencies andleanings it would be of great value. butfew have the opportunity to find outthis information. The next best thing.would then be to develop your own

policy as to giving and stick to it reli-giously.

A budget system could be a prime as-set to that policy, if charity allotmentswere figured into the yearly budget ofthe business, indicating the maximumamount that could be afforded, keepingin mind those limitations imposed fortax purposes.

Point two of the policy could includethe division of the money set aside forcharitable purposes, into groups of fav-orite charities in your community. Ifthe community tends to lean heavily toone particular fund drive, donate themajor portion to that and divide therest among the smaller charities. Itwould be wise to set -aside a smallamount for the unexpected that mightoccur, such as a local tragedy, etc.

Some shop -owners prefer to give onlyto those individuals who make personalvisits to the shop in request for dona-tions. All other requests made out -of -person are ignored and in -person re-quests are given contributions with theunderstanding that it is the most thebudget can afford.

The giving of merchandise to replacecash donations can be extremely bene-ficial to both the organization needingdoor prizes, etc., and is one of the mostsuccessful and often times overlookedideas. The merchandise gift itself looksmore than actual cash and the mer-chandise is displayed. where partici-pants in the affair can most readilysee it. Perhaps the organization spon-soring the benefit will even give yourecognition by displaying your callingcard atop the merchandise. What couldbe a more perfect method of advertis-ing?

It is found that some shop -ownersprefer to work a two-way proposition tobenefit a particular charity along withhis employees. customers, or young chil-dren in the vicinity of the shop. It

works something like tlis - wheneverthere are charity tickets being soldthe dealer hurriedly buys up his shareand in turn gives them away to thosehe feels are most deserving. The charitybenefits from his thoughtful contributionand he gains goodwill from the peoplewho in the end will entertain them-selves with the free tickets.

Buying- advertisements included onthe programs of charitable events is

risky business, especially if there arenumerous events such as this in yourcommunity. Stay clear of favoritismadvertising in one and not the other -this generally causes and an in-dication of your partiality. If it is im-possible to advertise in all such publica-tions it would he better to contribute insome other less conspicuous way, how-ever if there arc but a few of thesecharitable events it is a favorable meansof advertising your business and help-ing financially with that charitableevent.

That empty store window that gen-erally is considered a trouble -spot canbe put to good use with a charitablewindow dressing treatment. Make surethat the poster material being submittedto you is in decent condition for dis-play purposes and by all means insiston the right to remove such a displaywhenever and for whatever reason youplease. I -rider such circumstances itwould be favorable to set-up both aninstallation and removal date. This win-dow technique has been found to liemost favorable as it draws attention toyour store and save a donation.

Being firm in your standards andpolicies concerning charities and chari-table organizations will bring nothingbut the highest extent of respect fromyour community. If a sound programand set of rules is established there canhe no possible reason for confusion, mis-understanding, or ill -feeling amongcommunity and your dealership.

Iry Tjomsland, Editor

HORIZONTAL SWEEP CIRCUIT MEASUREMENTS:3-1: THEORETICAL OR PRACTICAL

The new man who enters the television service field willsoon encounter horizontal and vertical sweep problems. Ifhe has a normal run of sweep defects he will solve someby adjustment, some by tube substitution, and some byreplacement of wired -in components. Unless he is unfor-tunate enough to encounter a number of cases of multipletrouble he may decide that eight out of ten sweep jobs areeasy, and if he does not find the work particularly inter-esting or challenging he may attempt to limit his efforts tothe simple jobs.

Why then. make such a federal case out of the balanceof the problem? Why study so hard to understand trace.retrace. blanking. the sweep cycle, and power conditions?

Is this just another instance of over -emphasis of the theo-retical when attention should be concentrated on the prac-tical?

3-2: BUSINESS ASPECTSThere are many good reasons why a through technical

inderstanding is important. but here are two practical, nottheoretical, considerations that may shed some light on thesubject.

FIRST: A performance record of 80% on sweep circuitservice is not good enough to build a growing customer line.because it is only fair to assume that the same man w illbe only 80% satisfactory on other phases such as nc,video, or audio problems. Service of this calibre could beexpected to cause loss of the average customer within threeyears, and it is doubtful if any kind of advertising or pro-motion work could bring in enough new customers to permitthe business volume to grow.

SECOND: If the new serviceman acquires a good fun-damental knowledee of raster characteristics he can sup-plement the hasi, AC and DC measurements with inval-uable information taken from the most convenient displayof operating results which appear on the face of the picturetube.

As mentioned in 3-1 the difficult problems will be relatedto repair jobs that call for solution of more than one defect,but since every individual trouble will not necessarily causeloss of raster it is entirely to return a receiver to a cus-tomer with "call-back" built in just like a time bomb!

The customer judges your work by the appearance of thepicture on the CRT, and you can avoid a lot of problemsif you better understood the part he looks at, and the lessobvious indications that can keep you out of trouble.

3-3: THE BASIS OF PERFORM ONCEThe purpose of this article is to try to convince the new

man that accurate measurement and careful analysis of re-

sults are important if business is to prosper, and the cus-tomer line to expand.

It is far beyond that capacity of this article to cover allphases of measurements and raster analysis. but an effort

ill be made to emphasize some basic factors AN ith the hopethat if enough interest can be aroused the new servicemanwill undertake further study in one of the excellent bookson the subject.

Good sweep service procedure is the art of reducing theunknown to a set of values that you "know for sure." Someof this data should be taken from your schematic informa-tion, and some should be developed by careful attention toyour method of test and the accuracy of your equipment.

34: AC LINEThe voltage and current data you find in your schematic

information is of utmost importance to fast accurate service,but it can he very misleading if you do make certain thatyou operate the receiver under test at the correct line voltage.

In the recent instrument calibration check sessions veryfew shops owned test equipment that would determine linevoltage within 5(;L let alone the necessary A 51(." er-ror will permit a 12 volt variation in your bench line vol-tage and this can change your plate voltage readings from6 to 30 volts. your boost voltage from 10 to 30 volts. andyour high voltage as much as 1 to 2 KV! You are defeat-ing your own purposes if allow such discrepancies becausewith such errors you have no methodical way to prove "forsure" that operating conditions are correct or incorrect.

Every new man who equips a work bench will makebetter progress if he w ill obtain a line .!I meter capableof 1'; accuracy. If he will add to this form of linevoltage adjustment device to establish his line voltage cor-rectly before proceeding with other tests he will avoid manyof the problems he will encounter otherwise.

3-5: PLATE SUPPLY OR "B PLUS"\lam sweep failures result from variations in plate sup.

ply i It plus) voltage. Excessive or inadequate width. highplate or screen current, and many other dangerous prob-lems start here. If you know that your line voltage is cor-rect, it follows that your plate voltage must be correct oryou have some form of rectifier deviation. Many a service-man makes a callback because he. or a predecessor. madean incorrect change of the power transformer. rectifier, orprotection system.

Most shop test equipment is fairly accurate in B plusmeasurements. but again it is hard to have too good ameasuring device. A safe tolerance for B plus is to lookfor a "plus nothing -minus five percent" situation. Platecurrent in the horizontal output stage may increase as much

JANUARY, 1964 11

as 1 milliampere per each volt of excess B plus. and 20volts excess B plus could cause an added 20 milliamperesto appear in the horizontal output tube.

Many receivers can endure this. although with shortercomponent life. but if the receiver is also asked to operateat a higher line voltage in the home the trouble will becompounded. If B plus is abnormal. try to locate thereason before checking further. Maybe a higher outputpower has been installed. maybe silicons have been substi-tuted for seleniums without compensation. or maybe theindividual receiver is off standard and the problem willhave to be cured before it will give the customer long lifeand good performance.

3-6: 61141ST VOLTAGEIf the line voltage and plate supply voltage have been

found satisfactory. the measurement of boost can be a veryvaluable addition to the facts vou "must know for sure."

According to 2-4 Wecember MESD I boost voltage is de-veloped at the boost capacitor as a result of recovery ofstored energy from the horizontal sweep cycle.

If the line and plate voltages are correct, the resultingboost voltage is very significant in that it is dirertly re-lated to the operating condition of the AC factors. such asthe inductance of the flyback and yoke, the circuit capa-citance. and losses in general.

The boost voltage present follows changes in drive. lin-earity or efficiency coil adjustments. and variations in secondanode current. Boost is usually lower at high brightnesssettings, and will vary with demands of other circuits suchas the vertical maimt load. so all other adjustments shouldbe normal when boost is measured.

Ltdess major components changes have been made. trou-ble should be expected if boost does not follow specifica-tion. If boost is low. the second anode supply will tend tobe low. brightness may suffer. and focus may be sub -stand-ard. On the other hand if boost is high. plate current throughthe flyback and horizontal output tube will tend to increasewith the ever present possibility of a flyback and tube "cook-out."

Many show voltmeters are inaccurate on boost measure-ments. Some meters. particularly early VTVMs may respondto the presence of RF at the boost connection and give er-roneous readings. Another reason for inaccurate readings isthe lack of comparison voltages. since it is not practical touse batteries for calibration purposes because of the largenumber of cells required.

A good point to remember is to adjust width. heighth.and brightness to normal values at the recommended boostvoltage. and if this voltage is recorded on the worksheet itmay be valuable for future reference.

3-7: HIGH VOLTAGEThe serviceman's evaluation of the receiver's picture

quality is dependent on the knowledge that the high voltageis at the design value. Contrast and brightness depend onadequate high voltage. and too many variables are presentif poor performance can be due to many factors such as apoor CRT. poor video amplifier. low signal. or poor highvoltage.

If the high voltage measurement is made and comparedto the manufacturers specification this factor can be elimi-nated and attention devoted to progressively checking otherpossibilities.

Lnfortunately. very few servicemen measure and recordhigh voltage. The main reason is that most high voltagecheckers are purchased as accessories. rather than as com-plete units. Probes suffer from excessive size and bulkiness.probably in the name of safety Iand superstition) but itseems odd that servicemen handle second anode leads withless than I/8th inch of insulation. but must have a four-

teen inch probe to measure the voltage inside the anodelead.

Many servicemen find it hard to buy a probe that has thecorrect resistance to \\ork with voltage ranges on the meter.and of course \\ hen the high voltage probe is connected itis usually necessary to remove the normal probe.

It is earnestly recommended to the new serviceman thathe obtain a good meter movement and the necessary resistorand probe to enable him to make accurate measurements inthe 5 to 30KV neighborhood. The cost will he minor com-pared to the benefits of accuracy. and the setup can be madelo be so convenient that high voltage measurements will beas easy to make and record as an\ other as any other test.3-8: RASTER ANALYSIS

\\ hen the operating voltages such as the line. plate. boost,and second anode voltages have been measured and record-ed. examination of the raster will reveal many details ofactual receiver operation.

As the new man gains experience he will make ever in-creasing use of the evidence on the face of the CRT. This iswell because this is also the point on which the customerwill rate the quality of his workmanship.

Obviously if the recei\ er has the correct high voltage. agood CRT should develop a raster of acceptable focus andline structure. or it will be suspect. It is a fact that quite afew picture tubes have been changed because the service-man did not realize that high \ oltage was low. If the serv-ice procedure had been methodical and such factors as line.B plus. boost. and high voltage had been known for sure. itwould be much easier to pin down responsihility for aninferior raster.

However there are many details of performance visibleby careful examination of the raster that are useful to theserviceman. In addition to the fact that it is advisable toknow more about the raster than the customer does. manyfactors are visible that may show the receiver to be in goodcondition, or be positive signs of future trouble. A coupleof examples will illustrate the point.3-9: HORIZONTAL BLANKING

In 1-10 horizontal trace time is listed as 56 microsecondsI abbreviated to usee I and retrace time as 7.5 uses. Trans-mitted blanking signals will be about 10 to 11 usec. andare intended to cut off the CRT illumination from a time2 usec. before the beam reaches the right hand side of thescreen. keep it cut off during retrace and for 1 usec. afterthe new line hare is initiated. 11-12 Nov MESD).

You the serviceman can easily verify this operating con-dition if you will &center the raster on a reeri\ er that doesnot employ horizontal blanking. If the raster is normal andthe receiver employs a 21" CRT this blanking area will be-come visible when contrast and brightness are adjusted.Video information will be seen to end about '21rds of aninch before the end of the line is scanned.

If the raster is again decentered to expose the left handside of the raster about 13rd inch of dark or blanked areawill be seen.

All very interesting. you might say. but how does it helpto make money or get the job done?3-10: VALUE OF INFORMATION

This information will help you make money by improv-ing customer satisfaction and preventing callbacks. Let usexamine a typical instance:

If instead of findin.r' 2 '3 inch on the right edge and 1/3inch on the left. you find 1 inch on one side and none onthe other you can be quite sure your customer will experi-ence "foleover" due to unblanke'd retrace. The effect maybe very elusive. for it may bother on some stations and noton others, or it may bother only on certain types of pro-gram material.

12 MODERN ELECTRONIC SERVICE DEALER

HORIZONTAL SWEEP CIRCUITMEASUREMENTS (c.a.,

If the blanking (1,,, - not occur both before and after re-trace, the beam may actually illuminate the screen slightlyduring retrace. The customer will describe the effect as"veiling" or "interference" and he will usually object tothe defect.

If all the blanking is on one side and none on the other,the problem will usually be solved by adjustment of the hori-zontal oscillator, correction of sync or comparison pulseproblems.

If inspection shows that almost no blanking is visible oneither side there is good reason to suspect major changes insweep components, wrong or excessive shunt capacity, orvariations in drive waveform, to name a few.

The important point is that a minute spent on this in-spection will help you know for sure that things are rightor must he corrected.

3.11: SI I )HT It ETIt ACE TIMELet's take up a more serious symptom: Too much blank-

ing time showing.It is not too difficult to find a modern television receiver

that can be altered to show much greater blanking time (byspeeding up retrace time). This may happen if normal ca-pacitance is eliminated from the flyback circuit and thisillustration will show how this can happen.

One manufacturer of replacement yokes was plagued byexcessive failures of insulation in a yoke that had given notrouble previously. The problem arose in many parts of thecountry which tended to eliminate local conditions such asline voltage or humidity as the reason.

Field investigation developed an interesting fact: The

failure was associated with one model receiver. Further in-vestigation revealed that when this series of receivers hadbeen in service about a year they might require a servicecall because of a "no raster" complaint.

The trouble was caused by failure of a 150 mmfd ca-pacitor connected across part of the flyback, and outsideservicemen found that this could be clipped out without re-moving the chassis. Since the picture was restored and ap-parently normal no replacement was installed.

Soon afterward the yoke would short, and many service-men would install a replacement yoke, also without remov-ing the chassis. The new yoke would last a few weeks, andthen it in turn would fail.

Apparently the removal of the capacitor shortened re-trace time with a consequent increase in surge voltage.Sharp voltage spikes of tremendous amplitude attacked allparts of the sweep circuit and caused the insulation to punc-ture. The first replacement was on the customer, but thesubsequent units were on the serviceman, distributor, andmanufacturer.

When a typical receiver was checked for blanking timealmost two inches of total blanking were visible with thecapacitor removed, and this returned to normal with thecapacitor properly installed. (And the same series of yokesgave normal service also).

3-12: CONCLUSIONThis material has not been presented with the idea that

you must make special raster examinations or you will bein trouble. Many such tests are very difficult due to inac-cessibility of centering, brightness or contrast controls, orthe presence of internal receiver blanking.

If you do, however, make use of orderly measurementsand inspections you will find that you encounter less "mys-teries" and more proved cures.

COLOR CRT CON

21 F B P 4 Substitution

For 21 AX P 22 AAnyone who doubts that the custom-

er gets his money's worth from the tele-vision service profession should see theearly color receivers after a color experthas converted a receiver to use the lat-est color picture tube. It isn't often thata customers television improves withage, but when the latest glass tube issubstituted for the early metal type the

improvement in brightness, contrastrange, and ease of performance is al-most unbelievable.

Does it take a lot of time, is it trickor complicated, or are there engineer-ing changes that must be made to doit safely?

The answer to all these questions isNo.

If you follow the suggestions of RalphJohonnot and Jimmy Songer of Tri-Color TV in Burbank (see photo) yourbiggest problem will be to substituteslightly longer mounting bolts for theoriginal boot.

If you use the RCA Glass ConversionKit you will find complete instructions.hardware, and latest style yoke adapterto simplify the job. A word of warningon the RCA Kit: This kit was broughtout when the 21CYP22 I A I was thelatest improvement. Servicemen will findthat the 21FHP22 will provide tremen-dous advantages over the already im-proved-CU' type.

As shown in the Photo Tri-Color cutout the segments of the hoot to providespace for the slightly rounded bell ofthe glass replacement. Now, several con-versions later, they advise that the topand bottom sections do not need to becut out, saving a few minutes more.

Servicemen who are tempted to re-place a metal with a metal color CRTmight remember that purity, converg-ence, and tracking are much more sim-ple with thr glass bottle than with themetal, and any lost time on adaptingthe glass tube is more than recoveredin the better and easier setup of thecompleted job. Then there is the own-er's side: Who ever heard of a cus-tomer that wouldn't appreciate the un-expected bonus of "double the bright-ness in a seven year old receiver"?

A final point: The new tube willshow a lot more of everything than theold dim job: It just won't deliver theultimate unless the tubes, controls, andadjustments are carefully checked and

i railed.

CTC-7

fERSION SERIES:

Quite a number of service shops inSouthern California have furnished dataon color CRT conversion of the CTC-7chassis. Bob Albright of Allbrite TVhas added some refreshments and hissuggestions are outlined here.MECHANICAL:

The mounting retaining ring tends tobe in the vicinity of the High Voltage(Ultor) connection, and as shown inthe photo Bob cuts out a 5" segment ofthe ring to remove any danger of coronaor arc -over. Since the ring is very stur-dy, adequate mechanical rigidity re-mains to hold the CRT under all condi-tions Bob has encountered.

The 21CYP22 required a dual Ultorconnection with a resistor connected be-tween the plugs. Since the 21FBP22 re-quires only one connection the resistorand extra plug are removed. Bob men-tions that the only problem he has en-countered subsequent to a conversion isone of corona if he uses the original"hook" connector. He recommends thata smooth "rosebud" type anode connec-tor be substituted.

The 21FBP22 offers greater contrastrange and Bob suggests that a slightcircuit revision be made to take advan-tage of this and also improve the al-ready easy tracking procedure. Thischange consists of disconnecting thegreen and blue cathode leads (yel-grnand yel-blue) from the original tiepoints on the tube cap assembly and re-connecting them to the red cathode lead(yel-red) terminal. He points out thatsome servicemen have attempted to ac-complish the same thing by simplystrapping the three connections together.Dont do it: It isn't the same, as youwill see if you examine the schematic,and you can expect no result to "smear"the picture slightly.

Many servicemen report excellent re-sults without making the change outlinedabove, which speaks well for the im-provement, but Bob says that if you domake the modification and then changeback you will be convinced.

What about convention maintenancework when the CRT conversion is done?

Again quoting Bob, be sure to checkthe adjustment of the Efficiency (Lin-earity) coil system. Most of the receivershe had modified have been out of ad-justment and he has been able to reduceplate current through the horizontal out-put by as much as 20 milliamperes.

Bad sockets on the PC boards havebeen the outstanding problem with theCTC-7 series. Wax from the powertransformer tends to run down thru the12BY7. NAW8. and 6AQ5 sockets.Don't try to repair the original sockets.but install improved replacements to

permanently solve the problem.Some servicemen might prefer to use

parts of the RCA conversion Kit for thisjob, because the yoke liner and coverwould change the yoke holder to thetype in the current use which clampsthe yoke to the neck of the CRT ratherthan mounts it to a separate harness.Others will find that there are a numberof ways to use parts of the early bootmaterial to insulate the mounting ringand prevent corona.

The fact that all experienced service-men appear to be in agreement on is theextent of the improvement: They all say"Muck better."

How To Talk

ANTENNAS TO YOUR CUSTOMERSBy ROBERT D. RAYNOR, President

Clear Beam Antenna Corp.

This is the final part of the Antenna Talkseries by Robert D. Raynor, President of ClearBeam Antenna Corp. During the past monthswe have received numerous comments on thisseries and want to take this opportunity tothank Mr. Raynor for his fine articles.

3. When your customer agrees, you step out to the front ofthe house and make as close an inspection as you canWITHOUT GOING UP ON THE ROOF. Fill out thecheck form completely, including the lower right handportion, which gives an estimate of the replacement cost.Be sure to use the form and to fill it out completely. It

serves to make the inspection and your recommendation moreofficial and has the added benefit of permitting you to offera quotation on the same sheet. When you are finished, ex-plain the points you have checked off in the "Worn Out"column and particularly the effect they have on the TV pic-ture. If your customer wants to wait and "talk it over withmy husband" you can leave the sheet with her. Remember.many husbands have an attitude that service people try tosell unnecessary repairs to women. With the Check Up sheetyour customer's husband can go out and "see for himself"that the antenna is worn out . . . and will have an ex-planation of why.

Being technically oriented, you will not have too muchdifficulty in explaining why an antenna is necessary. how itworks or why it should be replaced. You may, however, feela little strange about opening what might be considered asales talk or how you can close the conversation on a sale.Here are a few sentences which you might try out on yourcustomers to see if you feel natural saying them. They'll helpyou get started and help you build sales. After you've triedthem. try developing a few of your own.

OPENING SENTENCES

how long have you had your present antenna?

that's about the best adjustment I can get at theset . . . how old is your antenna?I notice Channel - isn't coming in too well . . .

which is probably because of the antenna. Wouldyou like me to check it?

The picture isn't as sharp as it could be, Mrs.Jones ... but with an indoor antenna it's about thebest I can do . . . Have you ever tried an outdoorantenna?

As I walked up to the house I noticed that you donot have an FM antenna . . . how's your reception?(Turn on set and get into discussion of how manystations she is receiving and how clearly.)

16

(111SING SENTENCES

or how to ask for the order: I

I have all the materials with me. Would you likeme to install it now?

Would you like me to replace the entire installationor just the necessary parts?

Would you like me to replace it with one just likeit or would you prefer one of the newer types withdura-gold protection?

If you like to save the installation cost I can offera complete kit and you can have your husband putit up . . . or if you'd rather not bother him I cando it for you now. Which do you prefer?

Considering the number of hours you watch TV eachweek. Mrs. Jones, a new antenna . . .

is like an investment in your entertainment . . . orcosts about the same as taking your family to themovies . . . or costs only 20 a day for the next

three years.

Would you like to install it while I am here?

AND THAT'S HOW EASY IT IS

To sum it up and help you keep it in mind, remember:

LOOK UP

TALK IT

PUT tip

. . . At your customers antenna before everyservice call. See if there are missing or sag-ging elements. corrosion or other signs ofworn out antenna. Chech also for an FM an-tenna and if there are one or two antennas.

. . . Ask your customer if she'd like a freeTV antenna check up. Explain how an antennaloses up to 50% of its efficiency after threeyears. Explain how much clearer their TV -picture will he with a new antenna.

. . . Carry antennas with you on your truckand make the sale right on the spot . . . orsell a Do It Yourself Antenna Kit. Rememberthe possibility of selling an FM antenna oran antenna for the second set.

So to increase your antenna sales . . and give yourcustomers better service . . .

BREAKS THE GAIN/OVERLOAD BARRIERServicemen and the public long wanted it, but were told they couldn't have it-atransistorized TV antenna preamplifier with the overload capacity to handle localsignals without sacrificing the gain that brings in distant stations.

But Jerrold did what couldn't be done. With the new twin -transistor SUPERPOWERMATE, you have, for the first time, a transistor preamplifier with the high gainand low noise figure that made the original Jerrold Powermate famous-plus anunprecedented overload capability for local -signal situations. SUPER POWERMATEoffers a gain range from 15.5db with 700,000mv max. output at Channel 2, to 11.3dbwith 200,000mv max. output at Channel 13. There are no tubes or nuvistors to replace.And frequency response is fantastically flat-a boon to color TV.

Sell new SUPER POWERMATE, the all -channel antenna preamplifier with G/O-theindustry's best Gain/Overload capability. List $44.95. See your Jerrold distributoror write Jerrold Electronics, Philadelphia 32, Pa.
