Wydawnictwa Komunikacji i Łączności, Warsaw 1972
This book introduces the reader, in an accessible format, to electroacoustic amplifiers intended for home use, such as an electric turntable amplifier, an electric guitar amplifier, a microphone amplifier, a mixer amplifier, a Hi-Fi power amplifier, and others.
The book provides guidelines for designing, calculating, and building electroacoustic amplifiers, with particular emphasis on transistor amplifiers.|
This work is intended for radio amateurs, music enthusiasts interested in electroacoustic equipment, and owners of electroacoustic devices who want to learn more about the operating principles and operation of amplifiers.
CONTENTS
Foreword (7)
A few years ago, I wrote the book "Electroacoustics for Everyone." Acoustic amplifiers are, out of necessity, treated rather cursorily. To fill this gap, I have prepared this book.
It is intended for anyone interested in electroacoustic amplifiers. It will help beginners understand the issues necessary to delve deeper into the subject. More advanced amateurs will find some guidelines for selecting the design and construction of various acoustic amplifiers. Radio engineers not specializing in electroacoustics will find a collection of basic principles for amplifier calculations and data on development trends.
This book contains a significant number of diagrams and descriptions of various amplifiers and their components, which can facilitate the construction of the desired amplifier. However, these are not recipes for building an amplifier without some basic knowledge and some practical experience in radio engineering. Therefore, completely "strict" amateurs should do some preparation before undertaking more serious assembly tasks. I hope that this work, although very modest in size and uneven in its depth of coverage, will contribute to the dissemination—especially among young people—of basic technical knowledge about electroacoustic amplifiers.
This third edition of the book is based on the second edition. Noticed errors have been corrected, the terminology has been adapted to current trends, and some of the diagrams described in the appendices have been modified.
