Très bien ! Un bouquin de référence à avoir dans sa bibliothèque si, bien sûr, on s'intéresse à ce sujet technique particulier !

5.0 étoiles sur 5 Fills an information gap for amp builders 5 mai 2012
Par Illinois Engineer - Publié sur

Good power supply design is as important to an amplifier as the ampifier circuitry itself, and while there are literally dozens and dozens of books on switching power supplies there appears to be nothing of value out there on the linear power supplies that we need to build tube amps. Now there is. Blencowe really covers the ground, starting with transformers and working his way through the various power supplies required for tube amps, and the various and appropriate forms of filtering and regulating the same. Even a chapter on protection and fusing and a chapter on various creative techniques to get the supply voltages you need from transformers you may have on hand! Much more information than you can get searching the net.

I'm an Electrical Engineer that doesn't do much analog work, and I welcomed the fact that all of the math was algebra, and all the explanations were strightforward to anyone that understands circuit analysis. I really believe that to get 100% out of the book you need to have at least an engineer's or a serious technician's background. That said, there are numerous circuit examples with part values, so the book can be very beneficial to just about anyone that can follow a schematic, solder a connection, and know how not to get electrocuted. I am predominantly interested in audio amps, not instrument amps, and this book is of equal value to both camps.

I like also the fact that Blencowe explodes certain tube myths that I have somehow come to accept, and which have obtained a life of their own on the internet. He talks about the myth of "cathode stripping", and provides evidence that this is a transmitting tube phenomena, and that this happens at an electric field strength level that almost never occurs in receiving tubes.

So I waited patiently for this book to arrive and wasn't in any way disappointed. Because of it I radically changed the power supply design for an amp I was designing and building. Just sorry I left the book in seat 7A of U.S. Air Flight 98.

Just flipping through this book now, there's an asterisk note at the bottom of page 134:

"* Although as Douglas Adams pointed out, never underestimate the ingenuity of fools."

Any book that cites Mr. Adams is swell by me, but even that aside, nowhere, and I mean nowhere, have I found a more comprehensive and up to date treatment of vacuum tube power supplies. There are whats, and also whys for the various schemes one can use. Explanations are given for some of the bugs/"features" of older amps, which can be designed in if desired, or removed completely. Blencowe gives equal treatment to both.

Having done publications and journalism throughout high school and college, I might also add that the book is very neatly laid out, with clear equations and consistent, freshly drafted schematics. Nary a mangled scan from some 1950s textbook can be seen here.

If you're keen to see what's in store before you buy, PDF previews are available on the author's website, here:


The rest of book is well worth it.

I had bought his pre-amp book before, and like that one, this book has lots of great information on an often ignored section of guitar amplifiers. Having said that, in my opinion you should already be fairly knowledgeable about amplifier building and operation, AND really be into this topic to buy this book. It is NOT light reading to say the least.

If you have built guitar amps as kits mostly and want to start doing your own designs, or just want to know better how power supplies work, this is a great book. If you are starting out, I would skip it until you have more knowledge, otherwise you may get overwelmed.

5.0 étoiles sur 5 Great in depth read on power supplies 29 décembre 2011
Par Fourtytwo - Publié sur
Format:Relié|Achat vérifié
Good organization of the topics, great discussion and descriptions of the physics, and proper development and explanation of the math involved. i have found that the topic of power supplies has been a sideline of many tube amplifier books and had to discover most of what i know through experimentation and trial and error. this book helped fill in the holes. only bit of negative feedback i would give is that the Maida Regulator does not like energization using silicon rectifiers and this was not pointed out. the fast on time means the pass transistor operation will be outside of its safe operating limits on the first cycle and it and the LM317 will not survive.

5.0 étoiles sur 5 Best Power Tube Amp Supply Book Ever! 21 décembre 2012

I'm an old amp builder, the Amplifier Wizard. Graduated tech school in the 60's
and building stuff ever since.

This book has stuff in it way beyond anything I knew or read about before and
answers a ton of questions about power supply performance that will help me
rethink all my misconceptions from the past.

If you build Hi-Fi amps or guitar amps using tubes or valves you need this book.
