Build Your Own AF Valve Amplifiers: Circuits for Hi-fi and Musical InstrumentsElektor International Media, 1995 - Всего страниц: 252 To many people, the thermionic valve or electron tube is history. However, whether it is nostalgia, interest in the technical parameters, the appeal of a gleaming amplifier chassis with softly glowing valves, respect for the technical know-how of an earlier generation, or perhaps the firm conviction that the sound of a valve cannot be bettered, it is a fact that the valve is making a come-back. The book contains, apart from construction projects for preamplifiers, power amplifiers, and two amplifiers for musical instruments, information on the operation of electron tubes, while the first chapter gives a short history of the valve. |
