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.

Yes, it looks complicated, but the operation is the same.

Much more information than you can get searching the net. Cover may bg represent actual copy or condition available. Vertical and horizontal grids. Website Introduction Welcome to the wonderful world of valve amps! Next, we move on to the series high-voltage regulator based on the LM Amplifidrs would use either a 10W resistor or two 5W 24k resistor in parallel. Donations gratefully received through PayPal. 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.

Suggestions, comments, criticisms welcome. 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. It may take a couple of years, however, as I am currently working on a different title. In conclusion, in spite of a few minor, very minor criticisms, I highly recommend this book, for beginners and masters alike. 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.

Design and Construction of Tube Guitar Amplifiers.

The LM will use all its considerable negative feedback to keep a steady 1. All of the above coupled with ocassional and quite tasteful doses of humor, amplkfiers this book a joy to read! It contained too many mistakes and typos, and it didn’t match the style of my preamp books. Interested in making your own ribbon microphones?


I’m sorry to say I permanently removed it from print.

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. 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! National Semiconductor makes or used to make a high-voltage version of the LM, which can withstand 47V between its input and output pins.

Designing Power Supplies for Tube Amplifiers

No, not a high-voltage negative regulator, which would be merely a mirror image of the above circuit, with PNP transistors replacing NPN types, my goal was a positive high-voltage regulator.

Withoutabox Submit to Film Festivals. 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.

Find it in a library. The LM really doesn’t know that it is the heart of an elaborate high-voltage positive regulator; all it knows is what is happening at its output and adjustment pins.

My guess is that the circuits are suppliew too naked, requiring more protection devices, such a resistor in series with the LM’s adjustment pin and some of the capacitors. No one asked me this question; I was just giving myself a brain teaser. Under the dust jacket, the book’s spine and its inner title page reveal the book’s true title, Designing Power Supplies fr Valve Amplifiers.

The 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.


Okay, if this last capacitor is so important, why are you using a cheesy electrolytic capacitor and why is it so large in value?

In addition, all the many schematics are cleanly laid out and easy to understand. For example, although he praises silicon thermal pads, so much tidier, he says nothing about the up to 1.

In vlave you can’t find the book you’re looking for on Biblio.

AmazonGlobal Ship Orders Internationally. If you have built guitar amps as kits designibg and want to start doing your own designs, or just want to know better how power supplies work, this is a great book. There was a problem filtering reviews right now. If you are a seller for this product, would you like to suggest updates through seller support? But the capacitor also terminates into the ohm resistor, which is effectively grounded at its other end.

My first thoughts were that it ampliifers certainly be possible to create a shunt regulator, such as the following.

How to design valve guitar amplifiers

There are whats, and also whys for the various schemes one can use. Note that a 1. East Dane Designer Men’s Fashion. If you are starting out, I would skip it until you have more knowledge, fro you may get overwelmed.

In fact, it was only in reading his explanation of calculating heatsink requirements that my eyebrows began to knit, my forehead furrowed. Share your thoughts with other customers.
