Before you've even gotten halfway through this book you can go out and fix half the television and radio receivers that come your way. The author, a long-recognized expert, shows how in a new and completely practical way. Every sentence is boiled down to give you facts in a hurry. And only those facts that will give you real help in testing and repairing sets are included.
The book begins the moment after you've decided to get into the money-making field of radio and TV servicing. It tells you what servicing involves... how to get information and help... and the tools you'll need on the job. You're told enough of how radio and TV sets work to help you talk to customers confidently.
Since many set troubles boil down to faulty tubes, you're shown how to check and replace them. Then the book goes into the troubles of power supplies, resistors, condensers, coils, tuning devices, and speakers. You are also shown how to install antennas and use test instruments. Every time you finish a chapter you've increased your know-how with practical, how-to-do-it facts. With a minimum of theory and mathematics, there is nothing whatsoever to get in the way of your understanding in the quickest possible way.
This edition contains much new information to keep you abreast of the fast-moving electronic industry... the expensive job of removing and replacing picture tubes, how to solder and repair printed circuits, testing and replacing transistors and crystal diodes, repairing clock-radio timers, practical coverage of ultrasonic, radio, pneumatic, power-line carrier and wire-line remote controls for television sets, and more.
You'll be able to fix three out of four sets when you finish the book. On the fourth you'll get valuable experience and still break even profit-wise, because the author tells you how to "farm out" sets with really complicated repairs to service shops that do the job on a wholesale basis for servicemen.… (plus d'informations)
