Abstract• This work looks into the issue of development of the
tube amplifiers. • This work also includes summary of its basic parts
and classes of the tube amplifiers. • In my work its written a principle of power-suply,
pre-amplifier and power amplifier. • Its also looks into reliability, security and quality of
connection.• The end of my work compares sound characteristics
of tube and transistor amplifiers.
Prečo elektrónka?Why vacuum tube?
• Čistota a spevavosť zvuku (clean and energetic sound)
• Zaujímavé skreslenie (interesting distortion )
• Nádych histórie (a touch of history)
• Vážna, Jazzová, Rocková hudba...• Rozšírenie vedomostí (expansion of knowledge)
Čo je elektrónka?What is vacuum tube?
• Napäťovo riadený prvok (voltage-controlled element)
• Obsahuje 2 a viac elektród (it contains 2 or more
electrodes) • Sklenená banka (glass bank)
• Vákuum (vacuum)
• Riadiaca, tieniaca, brzdiaca mriežka (control, suppresor, screen grid)
Základné údajeBasic information
• Trieda AB (class AB)
