For over half a century, valves (or tubes) dominated electronics. They could be found in televisions and computers, communications and medical equipment, and in the radio set in every home. Since the advent of the transistor and the silicon chip, valves have almost completely disappeared. Valves, however, are still the preferred device in specialist applications involving high power, including microwave ovens and some transmitters. There are enthusiasts who believe that valve audio amplifiers give a more accurate and pleasing sound than semiconductors.

With Valves Revisited you’ll learn the basics of how valves work and 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 of valves in amplifiers, receivers, power supplies, signal generators, guides to modulation, receiver design, measurement, and fault finding. If you want to know more about valves, plan to restore a classic vintage set, or even to build valve equipment from scratch this is the book for you.
