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.

Thus, its maximum power dissipation is only 0. Starting with the compulsory throat clearing, let’s look at two old designs. East Dane Designer Men’s Fashion. Much more information than you can get searching the net. An essential handbook for any valve amplifier enthusiast! The low-voltage regulator establishes and maintains the fixed output voltage, while the high-voltage triode shields the solid-state device from lethal voltages.

Mr Broskie, I bought an Aikido stereo linestage kit from you some days ago, and I received it just this Monday. 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. Perhaps, I am making a Maugham out of a molehill, you know, Somerset Maugham as few readers are likely to read this book in a single sitting as I did and his prose is still far more spritely and readable than any modern electronics textbook I have read—and I have read plenty.

Numerous practical circuits ddsigning 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. High-quality, double-sided, extra thick, 2-oz traces, plated-through holes, dual sets of resistor pads and pads for two coupling capacitors.

Note that a 1. Beginners should read the first five chapters over and over again, as they cover essential material, such as transformer selection, rectification, and filtering; particularly, the chapter on LC smoothing filters, as most tube fans know nothing about the problem of LC resonance.

Having done publications and journalism throughout high school and college, I might also add that the book is designong neatly laid out, with clear equations and consistent, freshly drafted schematics. Many pure tube-based and solid-state-based and hybrid solutions are illustrated; there is even a quite Janus-like shunt regulator that utilizes both feedforward and feedback to produce clean, steady DC voltage, page ; And the last chapter is a must read, amplifierw it covers the problem of too little or too much wall voltage and some possible solutions.


How to design valve guitar amplifiers

Blencowe’s over reliance on a somewhat passive and circumlocutory exposition wearies. Although the negative bias voltage tap is usually only found on big power transformers that were intended for use in tube power amplifiers.

Under the dust jacket, the book’s spine and its inner title page reveal the book’s true title, Designing Power Supplies for Valve Amplifiers. I’ve been getting a lot of mail about my power supplies book. This site is always under construction. One person found this helpful. What intrigued me was this question, Is it possible to make a high voltage regulator based on an LM? It is relatively easy to find introductory information on how to design simple amplifier stages, and it is also fairly easy to find extremely advanced information on complex circuit design, and nearly all of it is intended only for hifi!

Alexa Actionable Analytics for the Web. Blencowe gives equal treatment to both. The power supply book is therefore unavailable until further notice.

After the first hundred pages, I felt like slapping him on the back and telling him, “Just spit it out man” and I am a rabid anglophile. No eBook available Amazon.

Just more satisfaction in the bag, there. 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.

I remember seeing this schematic in an old National Semiconductor data sheet over 30 years ago. The LM is in control, measuring the output voltage and applying corrections as needed. Thus, they give us too little—for our own good, as they see it.

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.


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. For example, although he praises silicon thermal pads, so much tidier, he says nothing about the up to 1.

If you already 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. Thus, his book wisely poewr switching power supplies, but generously covers tube rectification, series and shunt regulation, and heater power supplies.

Vertical and horizontal grids. Speaking of guts, here is what those three pins connect to internally.

Building valve amplifiers is also more addictive than nicotine; you have been warned. Tips for successful searching Try checking the spelling of words in your search Try to eliminate “noise” words, such as a, and, the, etc Try searching by just one parameter at a time e.

He knows that most solder-slinging audiophiles stumble when it comes to designing and building a power supply for their project. Cover may not represent actual copy or condition available. Get to Know Us. Firstly, I’m extremely impressed at the quality of what I’ve been sent.

I’m sorry to say I permanently removed it from print. Wanted to let you know that this is simply the best PCB I have had in my hands, bar none. The Elliott Sound Practices web site offers wonderful heatsinking explication, guidelines, and design practices. But that doesn’t mean we can’t help you find the book you’re looking for
