Design and construction of a tube guitar amplifier
Šona, Štěpán ; Dvořák, Jan (referee) ; Kubánek, David (advisor)
The text of this bachelor’s thesis deals with the design, simulation and construction of a tube amplifier for electric guitar, based on the well-known guitar amplifier VOX AC 30. The theoretical part deals with the design and simulation of the original circuit. Subsequently, adjustments were made on both channels and simulated. The practical part of the work already deals with the construction itself, measuring the finished guitar combo. Frequency modulus characteristics, harmonic distortion, spectra and time courses of signals for distorted and clear channel were measured. Then the measurement was evaluated.

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.

Guitar electron-tube amplifier
Kokolia, Martin ; Petržela, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
The objective of this bachelor’s thesis was to design a low-frequency tube amplifier optimized for use with electric guitar. The preamp is equipped with ECC83 triode tubes as voltage amplifier and cathode follower for connection with a simple frequency corrector. The output of the FX loop allows the connection of external effects. The power amplifier is realized by dual-action 6L6 tubes and phase invertor with ECC81 triode. Output transformer allows impedance matching for speakers. The power supply uses a GZ34 rectifier tube and diode bridges. Text of thesis also includes theoretical design of guitar tube amplifier and documentation of realization of functional prototype.
