1. The heavy lines on the schematic denote the primarysignal path.
2. Unless otherwise noted, all voltages indicated on theschematics are measured under the following conditions:a. AC input at 120 volts, 50/60Hz.b. All voltages are +/-10% with respect to ground. A high impedance (10 megaohm) voltmeter must be used.
4. On PC board drawings, Square pad indicates:a. Polarized Capacitors - Positiveb. Diodes - Cathodec. Others - Pin 1
5. WARNINGParts marked with the symbol have criticalcharacteristics. Use only replacement parts recom-mended by the manufacturer.

TUNER ALIGNMENT PROCEDURE
AM ALIGNMENT PROCEDURE1. Connect an AM Signal Generator to the RAA1 ”EXT
ANT” pin of the 5 pin connector. (Refer to Page 110.)Connect a Distortion Analyzer to the MHT200 rear panelTUNER INPUT RCA jacks. (These jacks act as theTuner Output.)
2. Tune to bottom of band, and adjust T11 (AM OSC Coil)for 3.0VDC at R46.
3. Tune to top of band and adjust C64 (AM OSC TrimmerCapacitor) for 26.0VDC at Connector R46.
4. Repeat steps 4 and 5 as necessary for a Tuning VoltageRange of 3.0 to 26.0VDC.
5. Tune the Generator and Tuner to 600kHz, then adjustCoils: T101 (AM ANT) and T12 (AM RF) for best sensitiv-ity. Note: Coil T101 (AM ANT) is located on the RAA1.It is labeled “L1”.
Note: Refer to Figure 1 while reading the below procedure.
FM ALIGNMENT PROCEDURE1. Connect an FM Signal Generator to Antenna Input.2. Connect Distortion Analyzer to the TUNER INPUT RCA
jacks. (These jacks act as the Tuner Output.)3. Remove Top Cover and AM/FM TUNER Cover. Turn On
the AC rocker switch. Press the red Standby button toturn the unit On.
4. Select Tuner with the Zone A selector knob. Put Tunerinto FM mode and tune to 87.5MHz.
5. Adjust L5 (FM OSC Coil) for 3.5VDC at R46.6. Tune to 108.5MHz and adjust C59 (FM OSC Trimmer
Capacitor) for 24.5VDC at R46.7. Repeat steps 4, 5 and 6 as necessary for a tuning range
of 3.5VDC to 24.5VDC at R46.8. Tune the Generator and Tuner to 90MHz and adjust
Coils: L2 (FM MIX), L3 (FM RF) and L4 (FM ANT) forbest sensitivity.
9. Tune the Generator and Tuner to 104MHz and adjustTrimmer Capacitors: C60 (FM MIX), C62 (FM RF) andC63 (FM ANT) for best sensitivity.
10. Repeat 8 and 9 until no improvement in sensitivity isnoted.
11. Tune Tuner to 90MHz with no RF Input and adjust T9(FM DETector Primary) for zero volts between TP1 andTP2 relative (connector J6).
12. Tune the Generator to 90MHz and adjust the RF Outputto 1000uV and 100% MONO modulation at 1000Hz.Then adjust T8 (FM DETector SECondary) for lowestdistortion.
13. Reduce the Generator Output to minimum and detunethe Generator so the Receiver picks up only noise, thenrecheck the voltage between TP1 and TP2 (connectorJ6). Adjust T8 and C65 if needed. If it is not 0+/-0.2VDC, repeat steps 11 and 12.If there is interferencefrom a station on this frequency, tune the Tuner to anearby frequency free from interference for this measure-ment.
14. Tune the Generator to 90MHz with a 1000uV output.Then switch the Generator to stereo (left only) and adjustT10 (FM IF Transformer) for the lowest distortion at theTUNER INPUT RCA jacks.
15. Switch the Analyzer to the right channel TUNER INPUTjack and adjust R71 (MPX SEParation Pot) for bestseparation (minimum output).
16. Switch the Generator to the Right Channel and theAnalyzer to the Left Channel. Adjust R71 (MPXSEParation Pot) and check for best separation (mini-mum output).
17. Disconnect voltmeter from TP1 and TP2 (J6). Reduce thegenerator output to 5uV and adjust R73 (STEREOSWITCH Pot) so the MPX light (Dot next to SignalStrength number) just comes on.
6. Tune the Generator and Tuner to 1400kHz, then adjustTrimmer Capacitors: C106 (AM ANT) and C61 (AM RF)for best sensitivity. Note: Trimmer Capacitor C106 (AMAMT) is located on the RAA1. It is labeled “C1”.
7. Repeat 8 and 9 until no improvement in sensitivity isnoted.
8. Note the initial position of R70, and then adjust R70 fullycounter clockwise. Tune the Generator and Tuner to1400kHz (20uV, 30% modulation), then Adjust T7 (AMIF) for maximum signal.
9. Tune the Generator and Tuner to 1400kHz (100mV, 30%modulation). Slowly adjust R70 clockwise until theMHT100 front panel signal strength display reads “9”.
10. Check both channels for signal to noise performance,and re-adjust R70 and as needed.

In the event it is necessary to repack the unitfor shipment, the unit must be packed exactly asshown below.
If a shipping carton or any of the interior partsis needed, please call or write the Customer ServiceDepartment of McIntosh Laboratory. Order parts fromthe accompanying list by part number.
Use the original shipping carton and interiorparts only if they are in good serviceable condition.
IMPORTANT - The four plastic feet must be
attached to the bottom of the unit so they will locate in
the four holes of the bottom pad. Two #10 x 2-1/4"
screws and washers must be used to fasten the unit
securely to the bottom pad and wood skid. Failure to
do this will result in shipping damage.
