    Stereofónny elektrónkový NF zosilovač Stereofónny elektrónkový NF zosilovač Presentation Transcript

    • Stereofónny elektrónkový zosilňovač Hi-end stereo tube amplifier
      • Pavol Kababik, SPŠ Elektrotechnická Košice
    • 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 údaje Basic 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)
    • Koncový zosilňovač Power amplifier
    • Korekčný predzosilňovač Correction preamplifier
    • Napájanie Power supply
      • TRAFO
    • Konštrukcia Construction
