The author covers some basic electronics topics and gives a very down to earth discussion of various amplifier stages and the pertinent characteristics of their operation. For the do-it-yourself amp builder this is a great introduction. The text is full of practical advice and pointers to help the reader achieve a successful design.However, this is a practical text aimed at the hobbyist or electronic tinkerer. Do not go looking for in depth theory or detailed mathematical analysis here, you won't find it. The electronic hobbyist will find a wealth of practical information but a trained electrical engineer risks being put off by the lack of in depth analysis and numerous broad assumptions made while discussing design. Some chapters are much better then others. It is much more informative to address them separately.The first chapter is a basic introduction to electronic principles for both passive and simple active devices. This is probably a good refresher for the hobbyist or tinkerer, but anyone trained in electronics or electrical engineering can safely skip the first chapter. Chapter two gives a very good discussion of the basic building blocks of tube circuits. This is arguably the best chapter in the book. The content of this chapter alone is worth the price of the text. Chapter three is a discussion of distortion in tube amplifiers. This chapter contains lots of practical information, but little detailed theory. This is good information for the hobbyist but the engineer will find the lack of rigorous analysis frustrating. Chapter four covers components. The chapter covers some basic information on various types of the different passive components and a very interesting discussion of tube construction. If you're new to vacuum tube technology the latter half of this chapter is a must read. Chapter five is a discussion of power supplies. The best advice I can give on this chapter is don't read it. The author clearly has made many measurements and done much experimenting. However, the conclusions he draws tend to be very misleading. The problem with this chapter is that the hobbyist will be mislead into bad design decisions and the trained electrical engineer will be frustrated with the conclusions drawn. I have been shocked by the incredible number of truly abhorrent power supply designs floating around the internet. Chapter five of this book explains where some of the ideas for these supplies have come. There are much better texts discussing power supply design for tube circuits. For a good practical guide to power supply design, try Chapter 14 of "Theory and Applications of Electron Tubes", by Herbert Reich. Chapter six is a discussion of amplifier power stages. The text covers the basics of single ended and push pull operation and then goes on to discuss several different designs. This chapter contains lots of good practical information. Be warned however, the author is clearly of the "push-pull" camp and if you tend to favor the "single ended" designs, prepared to be insulted. The book finishes up with a chapter on preamplifiers and line stages. Included here are some good discussion on RIAA equalization. If your interest goes beyond the power amp to the entire audio chain, this chapter is very informative.Even as a career electrical engineer I gained significant information and insight by reading this book. It refreshed my knowledge of tube circuits and if I had this book when I was building tube amps in High school in 1980, my success rate would have been significantly higher. Overall this is a excellent text despite the flaws mentioned above. Whether degreed Electrical Engineer or avid hobbyist working on building tube amplifiers, this text is a worthwhile addition to your technical library. ### ⭐⭐ This book is supposed to be highly recommended. I am very disappointed *by A***N on Reviewed in the United States on November 27, 2014* This book is supposed to be highly recommended. I am very disappointed. I don't expect this book get deep into theory as you can use RDH4 for that. But I do expect the book should compare different circuit topologies, analyze the strong and weak point, distortion characteristics under different operating conditions so people can make a better decision. But this book has very little of that. Problem is there are very few books on tubes as it's not popular. You might get just as much if not more info by searching on the web. ### ⭐⭐⭐⭐ A good place to start *by E***N on Reviewed in the United States on July 22, 2009* The second edition of this book was the first book on tube amps I ever read. I borrowed it from the local library. I can not say that I understood all the concepts then, but for some reason whenever I had returned the book to the library there was something I had to look up, so I bought the third edition.There are not very many good tube books out there, you can believe me because I have read everything from the 1956 RCA tube manual to most of the modern books on the subject.This book is not perfect. It has the tendency to hide a lot of information in the text instead of making a clear presentation from point A to point B. It assumes that you have read all the preceding chapters and have them fresh in your head because there are explanations on things in chapter 13 that is based on stuff in chapter 3 with no references what so ever.That said, I think this is probably the best place to start. It has lots of information that is relatively easy to grasp.If you are more interested in guitar amplifiers, then I would not recommend you to start with this book. It has all the basic information you need to design a guitar amplifier, so it is not bad reading, but I would recommend you to buy "The Ultimate Tone" series (probably start with volume 3)by Kevin O`Connor instead. Because it explains more of the guitar concepts, such as how to make distortion sound good.If you want to design tube amplifiers I recommend this book. Even though I have many tube books this is the one I always come back to when I want to look something up. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/137391246-valve-amplifiers](https://www.desertcart.be/products/137391246-valve-amplifiers) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-23*
