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.All components, except the two transformers, choke L\ and the two high-voltage electrolytic capacitors, are housed on the printed-circuit board shown in Fig. 7-3. It is advisable to fit the wire bridges first, followed by the resistors. Next come the anbsp;...
