I have a bit of trouble writing this review because the Pre-amp book by the same author was so great and I don't think this is quite so good. Unlike the pre amp book is not packed with much brand new information i.e. if you read lots of books on valve amps you'll get most of it. However as a one-stop-shop book to read it is top notch so 5 stars.

There is some very good stuff on things like fuses - dull but remember your dealing with big DC voltages in valve amps so better you know why you should get a sand filled ceramic fuse rather than a glass one?

Also other stuff like how to get rid of diode noise in rectifiers the best. Useful for solid state amps too.

My only disapointments were (A) that switch mode power supplies seem to be regarded as a no-go area. Yes, I know they can be horrible but they have many advantages. (B) when I see a diagram of how to wire up a 78L12 linear regulator with an extra diode to get a 12.6V heater supply (or whatver it was) I cringe - we can all read data sheets.

Overall if you want to design a valve amp (guitar or hi-fi) and have not read lots on the subject already this is a great buy.

This book is an excellent resource for anyone who wants to build their own guitar amp projects, or just for getting a better understanding of how things work.

Merlin doesn't get bogged down into maths, but gives excellent explanations of how things work, with plenty of worked examples. However, he includes full references if you need more details.

With the help of this book, and the companion on Preamps, I've started building my own amp projects that have worked out as expected.

I highly recommend these books to anyone interested in the subject. Thanks Merlin!

Having cut my teeth fixing my neighbors failing radiograms and point to point SW radio construction on the bedroom floor as a teenager in the sixties I only got back into messing around with valves when my Chinese SET failed recently, resulting in some diagnostics, repair and the inevitable upgrades.

Having stacks of old books on valve circuits and of course Morgan Jones' essential volumes I was in two minds about bothering with this book and it hovered on and off my wish list for quite a while.
Having now taken the plunge I have no hesitation in recommending it. It is readable, informative and easily understood. OK some paragraphs may take a reread to fully grasp but what technical book doesn't. Bought mainly as a refresher course it is in fact extending my knowledge on the subject which is a pleasant surprise. It is much more detailed than your average how to book, delving into the underlying theory.

It does have the usual Health and Safety caveats, which given my upbringing in the art are considered amusing if not entirely over the top and I certainly have no interest in whether or not a transformer-less design is "illegal" in certain jurisdictions, just whether or not one can make them work but these modern hangups are not the author's fault.

The author's initial tendency to use too may words quickly diminishes as the you get into the book.
All in all highly recommended. If you are new to the subject, it's up there with the essentials.

There is no doubt that this book is a must for anyone embarking on PSU design for valve amplifiers who is not already 'in the know'

The absence of an index means I am docking off 1 star. I would have also expected either an appendix with the .Models for PSpice or a link to a website to the book containing this information. Annoyingly, some PSpice models for the components referred to in the book are difficult to track down. So another star lost.
