Valves Revisited
For over half a century, valves (or tubes) dominated electronics. Since the advent of the transistor and the silicon chip, valves have almost completely disappeared. They could be found in public address systems and hearing aids, televisions and computers, communications and medical equipment, and of course in the radio set in every home.
There are hi-fi enthusiasts who argue that valve audio amplifiers give a more accurate and pleasing sound than those using semiconductors. However, valves are still the preferred device in specialist applications, usually involving high power, including microwave ovens and some transmitters. Valves Revisited is a wide ranging book that provides the basics of how valves work through to how to build your own.
There are details of the use of valves in domestic radios, test equipment and amateur transmitters. There are also detailed descriptions of the use
