For over half a century, valves (or tubes) dominated electronics.
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. Since the advent of
the transistor and the silicon chip, valves have almost completely
disappeared. However, valves are still the preferred device in
specialist applications, usually involving high power, including
microwave ovens and some transmitters. There are hi-fi enthusiasts
who argue that valve audio amplifiers give a more accurate and
pleasing sound than those using semiconductors. 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 of valves in
amplifiers, receivers, power supplies, signal generators along with
guides to modulation, receiver design, measurement, fault finding
and much more
