Do someone know where I cans find the “Designing Power Supplies for Tube Amplifier” by Merlin Blencowe book in USA?? Designing Power Supplies for Valve Amplifiers is a unique guide to the operation and practical design of linear power supplies, especially for valve equipment. I’ve been getting a lot of mail about my power supplies book. I’m sorry to say I permanently removed it from print.

Would you like to tell us about a lower price? If you are a seller for this product, would you like to suggest updates through seller support? Designing Power Supplies for Valve Amplifiers is a unique guide to the operation and designiny design of linear power supplies, especially for valve equipment. Audiophiles, guitarists and general hobbyists alike will find this book an invaluable source of detailed information on transformers, rectifiers, smoothing, high-voltage series and shunt regulators, and much more.

Although this book is not intended for the beginner, learning is encouraged through practical design, and concepts are introduced at a basic level before the reader is accelerated to the stage of high-performance design, with over circuit diagrams and figures.

Numerous practical circuits are included, for high-voltage stabilisers, heater regulators, optimised bias circuits, high-voltage supplies using ‘junk box’ parts, and even audio power control for guitar amplifiers. An essential handbook for any valve amplifier enthusiast! Read more Read less. Customers who viewed this item also viewed.

Please try again later. This is a really great book on designing linear power supplies in general not only tube power supplies, of course theres an emphasis on power supplies for tube amplifiers but the material covered by sipplies author is not restricted to tube amps.

The book covers a wide range of topics starting with the simple transformer, up to rectification, types of rectification, and beyond, which include transistors, opamp, RLC networks, grounding, etc If you are into audio power supplies or linear power supplies, this is a book for you, regardless if you are building a solid state amplifier or a tube amplifier.

Va,ve thing I find most amazing about this book is that it covers the rigorous part of the theory quite well while adding a “rule of thumb” and “tip of the trade” approach which further enhances the understanding of the topics, that being said many of the stuff covered in this book is not the typical stuff you will find in an electric circuits book or taught by a professor at the university, for example how to perform tests on an old transformer to determine its nominal working values.


If you mrlin have some knowledge on the academic side of electronics, then this book will make you awe on many of the design tips the author offers, its like having an experienced circuit designer teching you the standard stuff while sharing his tricks. The math amplifierx quite simple if you are the EE type, but it might be a bit too much for a beginner.

Eventhough you are not really required to perform drill excercises such as a regular textbook, the author makes use of concepts from calculus, vectors, electric circuits, and electromagnetism, so I agree with what the author wrote on the back cover: All of the above coupled with ocassional and quite tasteful doses of humor, makes this book a joy to read!

It is a true shame that this book is no longer in print, I checked the author’s webpage and this is blejcowe I found: Ampliifiers been getting a lot of mail about my power supplies book. I’m sorry to say it has been removed from print because I don’t like it. It contains too many mistakes and typos, and it doesn’t match the style of my preamps book. Now, before you ask, I do intend to update it eventually. It may take wmplifiers couple of years, however, as Meerlin am currently working on a different title.

And before you ask your next question, no, it isn’t about power amps. I won’t be writing about those for even more years! I’m sure this is a big disappointment to many readers, but that’s just the way it is. One man can only do so much!

The power supply book is therefore unavailable until further notice. Do not email me asking if I have spare copies or PDFs; your email will beignored.

One person found this helpful. 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 supplis be nothing of value out there on the linear power supplies that we need to build tube amps.

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.

Designing Power Supplies for Tube Amplifiers

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. That said, there are numerous powerr 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 resigning 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 ampliflers 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. Just flipping through this book now, there’s an asterisk note at the bottom of page 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. 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 s 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: 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. See all 19 reviews.
