 Definitive, don't build a tube amp without this! Oct 02, 2004
By Bighairydoofus
"-"
I recently purchased this, the companion work to the author's definitive book on tube amp design, Valve Amplifiers. There are quite a few books on how to design a tube amp, but very few resources available on how to safely construct them. I say safely because vacuum tube amplifiers use voltages that are lethal, some extreme designs using voltages in excess of a kilovolt! Safety is essential when dealing with tube amps at all times.
Originally, the author covered amplifier construction techniques in the first edition of Valve Amplifiers, but that volume is now in it's third edition and is over six hundred pages long WITHOUT the construction section. It's understandable that Mr. Jones decided to put out a separate tome on amp construction, since the construction information is as long as the entire first edition of Valve Amplifiers.
This book goes into great detail on how to build a chassis, wiring techniques, PCB's, metalwork and assembly using only hand tools. Examples are given of tools to be used (often with more than one choice for a given job) and how to use them properly. The book then goes on to explain the use of oscilloscopes, distortion measurements and troubleshooting, completely illustrated with pictures and drawings needed to do these things. There are also useful tricks, such as using a discarded radio tuning capacitor to find the optimum capacitance for feedback compensation.
This, along with Valve Amplifiers, are the definitive modern works for the amateur on how to design and build tube amplifiers. If you're interested in tube DIY audio, there just aren't any substitutes for these books, they're simply the best currently available, period.

 shop and compare Feb 12, 2005
By Frank Elliott
"Captain Fitzroy"
It is safe to assume that if you are considering this book, you feel you have ingested enough theory and are now ready for the nuts and bolts of assembling a vacuum tube amp of your own.
(Not the least of which regards the critical importance of safety when dealing with lethal voltages)
My rating of this book is a little low, inasmuch as the buyer might be disappointed to see so few words about assembly, and so many more chapters of theoretical/empirical esoterica. The author here is no slacker. He obviously has spent a lifetime in the field and has a vast body of expertise to share; and does so in that ever popular British circumlocutive amble. There is indeed a lot of subtle minutiae in the book that is informative, entertaining, and edifying. But aren't we interested in what to do and what not to do and why we do it this way and not that way regarding assembling the actual components? You can find all that info in this book; including what tools will help immensely and save a lot of starting over, and cursing inanimate objects on the way to starting over.
(and be encouraged to discover that even this practised author, Morgan Jones, has a bit of dread when he first powers up-hoping not to see sparks & smoke!)
But there are a couple more books that you might also consider:... On precisely what is taking place in a tube amp, one can do no better than to make sure to have on your electronics shelf, An all American classic by the late great USAF Colonel John Rider (of Rider Technical Publication fame)-a reprint of his superbly well written "Inside The Vacuum Tube". He takes you one step at a time; and at the beginning of a new chapter, reviews "what we learned, and explains what we will now learn and now build upon in the next chapter". In other words, it is a very well thought outand in depth treatise, with a beginning a middle and an end. You will emerge with a command of vacuum tube circuitry.
Once that is digested, ...and perhaps you are precisely at that point now... you want to know exactly why you use this value of resistor, and that value of capacitor, and this arrangement of components, and not THAT kind of resistor, etc,.. and I do mean exactly how...you will find no better book than another fine reprint by the title of "Mullard Tube Circuits For Audio Amplifiers" If it comes down to choosing one over the other, with both time and budget concerns...I'd go for the Mullard book, hands down, nol contendre. It gives all the exact reasons for why we provide feedback, precisely how the phase splitter splits the signal for the push pull, and why we even want a push pull rather than a single ended amp; and diagrams for drilling out the chassis, and time honored, and tested methods of assembly. 'S alright? 'Salright!

 Useful practical guide to building amplifiers... Dec 28, 2004
By sir_isaac_newton
...this book contains a lot of good, hard to find advice on the pratical issues that arise when building a tube amplier. This allows the novice to learn quickly without having to learn only by their own mistakes (which can be dangerous, frustating and costly). There are useful discussions on choosing basic equipment (although perhaps a little too much) such as Digital Volt Meters and Oscilloscopes. The author also usefully discusses sourcing components which is, in my experience, the big hidden work item you run into building your own electronics (especially tube electronics) these days.
This book, sensibly, does not contain a lot of theory (the author moved that to his other book -- which I did not find useful) or circuits for re-use -- but for the practical issues of safely producing a safe, robust, low noise amplifier this book is very good.
My interest is primarily guitar amplifiers and this book is equally applicable to that domain as it is to hi-fi amplifiers, albeit without any special consideration of guitar amplifier issues or circuits.
The authors writing style is fine (it could, perhaps be more concise in some areas) but the pictures and layout of the book are dated and, given that, the price seems high (although this book represents better value than the author's theory book, in my opinion).

Valuable if you already sort of know what you are doing. Jul 18, 2008
By Anthony Serino
For your own good, don't take the advice of people saying that this book is "great for beginners" etc. A background in electronics will help you, but an understanding of general amplifier design, practices and layout is assumed by the author and this book may be over your head at parts otherwise. Also, the author is british, so he'll write something like HT and you may not know that that means high tension which is britspeak for high voltage.
Also, I was hoping to get a solid guide on circuit design as well as amplifier construction and layout, but the circuit design is almost completely absent. Perhaps this is too much to ask for... after all it's "Building Valve Amplifiers" not "Designing Valve Amplifiers." If you want to design and build an amp, this book is only the second half of the solution.
With that said, it is probably one of the best resources once you reach the build phase of your project. The author gives numerous valuable tips to avoid humming, distortion, shocks, and all other negativities that can occur with tube amps.

A book about BUILDING NOT DESIGNING amplifiers Jan 14, 2012
By Charles Deluca
"cddeluca"
Building Valve Amplifiers is an indispensable book for an amateur learning to construct amplifiers on his/her own; it even includes examples of manufacturer design flaws and how they could have been avoided. The book presupposes no knowledge about electronic/electrical assembly at all and is an excellent introduction.
Two cautions:
(1) After reading many reviews it seems only a few people understand that this book is volume 2 of 2. Volume 1 of 2 is "Valve Amplifiers" Valve Amplifiers, Third Edition and it deals solely with amplifier design - this book does not contain any significant discussion of design principles.
(2) Some reviews seem to be negative for the sake of being negative - one reviewer writes that they have 20 years of experience as an electrical engineer and that they are disappointed in the scope of the book. I would hope an engineer with 20 years experience would be capable of writing such books, not buying them to learn the basics. Take the negative reviews with a healthy dose of salt: as an engineer with 35 years of experience I think Mr. Jones' two books are pretty close to masterpieces for the non-professional.
