Beginner's Guide to Tube Audio Design by Bruce Rozenblit - code 3004

If you have been intrigued by the rebirth of vacuum tubes as a way of reproducing music but are totally mystified about vacuum tubes and what they do, then Bruce Rozenblit wrote this book for you. This book is the best beginner's guide available on what vacuum tubes do and how to use them. Bruce shows you how to design the building blocks which turn tubes, resistors, capacitors, transformers, and other hardware into amplifiers which make beautiful music reproduction possible.

On the other hand, if you've been using tubes for years, can read a schematic, and have assembled several amplifiers or preamplifiers, but never quite understood just what was going on in all that nice circuitry, then Bruce's book can unveil all the mysteries of amplification which you have wondered about all this time. Author Rozenblit starts with a simple, clear explanation of what a vacuum tube is, and how it works. In simple language with no unexplained jargon, he steps through the basic types of tubes, what tube characteristics mean, how to read those funny charts, and understand specifications.

Systematically the author steps through single one-stage amplifiers, how to build a simple gain circuit, what negative feedback is, what it does, and how to use it. From there it's on to single-stage feedback circuits, multistage basics, a tour of amplifier parts of all types, what output stages and transformers do (including the newly popular single-ended types), and such variations as triode and ultralinear operation.

Next, the author walks the reader through power sources for the amplifier dealing with how power supplies work, how to build regulated supply types, all you'll need to know about the variety of power designs, and how to use each of the components needed in them. You'll not only understand how they work but how to fine-tune them to perform at their best. There are final chapters on stabilisation, testing, and how to work effectively as a designer; followed by a chapter describing just how 13 world-famous and classic amps and pre-amps work. A final chapter is a hands-on guide to construction techniques, tools, and choosing components and tubes. A special final supplement includes three working designs previously published by Mr. Rozenblit in Glass Audio magazine with complete instructions on how you can build them yourself.

Bruce Rozenblit is a graduate electrical engineer, owns and operates Transcendent Sound, a high-end amplifier manufacturing company, and has recently been awarded U.S. Patent No. 5,604,461 on a sophisticated new power amplifier. He is a frequent contributor to Glass Audio magazine.
