Pavol Kababik, SPŠ Elektrotechnická Košice

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)
