Design and properties of low-frequency amplifier with vacuum valves
Piroha, Ladislav ; Musil, Vladislav (referee) ; Šandera, Josef (advisor)
The purpose of the bachelor’s thesis is explanation of theory and construction of low frequency tube audio amplifier with UV meter. Main focus is on history and development of vacuum circuits from its early beginning, on electrical parameters and applied physical principles. Explanation of operating characteristics of amplifier classes and comparison of vacuum tube sound acoustic performance against transistor amplifier one. Finally, there is build description of single ended amplifier class A.

Valve amplifier for guitar
Hrabaň, Václav ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
Bachelor thesis deals with design, simulation and construction of guitar amplifier circuit with valves as active devices. Thesis describes in detail one of possible conceptions of a two channel amplifier with switching of clean and overdrive channel. Design contains input amplifier, two switchable preamplifiers, inverter, power amplifier, switching circuit and supply unit. Preamplifiers contain each their own frequency filter and regulation of gain and volume. Power amplifier works in class AB and its power is 40 W.
