[.ca] Power Vacuum Tubes Handbook, Second Edition (ISBN 0849313457)

PRICELESS CLASSIC!:
Anyone attempting to build a high-power RF amplifier MUST BUY THIS BOOK. (Yes, I mean the new second edition.) In spite of various nonsense spouted by semiconductor manufacturers and semi-competent engineers, vacuum tubes still are extremely valuable in all high-power RF applications. Tubes tend to be LESS EXPENSIVE than transistors, more reliable than transistors, and easier to use than transistors--especially at frequencies above 500 MHz and/or power levels above 10 kW. This book is the best ever written about power tubes and their use. Even if you are interested in audio tubes, there is much to learn from this book. --Eric Barbour, Svetlana Electron Devices, and editor, VACUUM TUBE VALLEY magazine

Oldies but goldies:
Vacuum tubes technology, a must for electronics technicians and engineers only 30 years ago, has limited its action to a few applications. One of them, and for artistical reasons, is audio amplifiers. But the main application nowadays, is RF high power amplifiers. Radio and TV transmitters, for example. One single tube is able to handle the whole power driven by the final stage of the transmitter. That is sometimes an adventage for engineers. But anyway, there still are thousands of transmitters in the world that are using high power tubes. I work on one of them, and this book is the ONLY ONE, and I mean this, that has allowed me to know the deepest secrets of this technology that, of course, was never taught to me this deep in college. By the way, the historical background the author gives us is very amusing. Read the book and you will know why.
