  2. 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.

  3. 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)

  4. 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)

  5. Základné údajeBasic information • Trieda AB (class AB) • Prepínateľné vstupy (switchable input) • Korekčný predzosilňovač (correction preamplifier) • Výkon 2x33W (output sinus power) • Výstup 4 a 8 ohm (4 or 8 ohm output) • Point-to-point (point-to-point wiring) • Dizajn (design)

  6. Koncový zosilňovačPower amplifier
