Amplifiers starts by providing the context of RF amplifiers with a detailed history and evolution of amplifiers and valves. The book also describes how valves work and the reasons for continuing to use them in amplifiers. Valve types are explored in depth along with classic designs from a wide range of manufacturers including Acom, Alpha, Collins, Drake, Heathkit and of course Linear Amp UK (the author Peter is the founder of Linear Amp), along with a number of others.
There are sections on fault finding in amplifiers and in depth details of Linear Amp UK amplifiers describing the evolution of the Challenger and Discovery models. Amplifiers then goes on to describe the design and how to make amplifiers for HF, VHF and UHF.
