Synopses & Reviews
This book has been prepared under the auspices of the G.E.C Valve and Electronics Department with the aim of presenting, in a readily accessable form, the essential details and circuit diagrams of a comprehensive range of audio-frequency amplifiers. All the designs reflect various aspects of modern technique and have been built and tested. In this field, the experience and accumulated knowledge of the G.E.C., dating back to the earliest days of radio communication and large power valve design, are unique.
Altogether seventeen amplifiers are described, ranging from a "junior" 5-watt ultra-linear circuit to an 1100-watt Class AB2 amplifier. In addition, various pre-amplifier units are discussed so that the information in the following chapters deals with all the equipment necessary between the signal source and the loudspeaker in most domestic, public address and industrial sound installations.
Since the book is essentially a work of reference it contains no constructional informationneither does it claim to be a text book, although as an exposition of modern design practice, it will be of comparative value in this respect.
