only about 1/4 of the book is relevant

I was excited when i ordered this book, but felt very let down when i started flipping though it.

Out of the 250 pages in this book, about 50 pages is spent on basic semiconductor theory on what resistors/capacitors/inductors/speakers/transformers are, how they are made, and the physics behind how they work.

Once you get past that part, there are some high level sections on tubes and pinouts.

One thing that made me scratch my head is that he spent so much time on basic fundamental theory which is irrelevant to the scope of the book yet he doesn't mention anything about tone stacks, buffers, chokes, or details about different transformers and their impact on sound. I realize that this isn't "how to design your own tube amp" but this book also isn't "introduction to solid state physics".

In the sections on tools and "what not to do" there was no mention of some other tricks like putting a light bulb in line with the mains to limit AC current

The voltage charts were handy.

Troubleshooting flowcharts and mods were worth the price of the book. As the author admitted, he has a bias for Marshall amps, so all of the mods use marshalls as an example: replacing the tube rectifier with diodes, adding a series effects loop, adding a master volume, etc.

All in all, this book could have easily been 1/2 the size and not lose any important information.

Not exactly what the title says

The author was good to add chapters on electronics. The troubleshooting charts are good to. What is missing is troubleshooting solid state components since this is what most amps are today.

 It's Already Paid for Itself

This book has already paid for itself by helping me with some issues I've been having with one of my amps and with a current build on a new baffled cabinet. I recommend it for those new to tube amps just for the wealth of information it gives you in regards to amplifier maintenance and troubleshooting -- even if you can't repair the problem yourself. The car and water analogies help make it simple to understand some of the terminology or concepts conveyed.

Good for Beginers

It is a good starting-point for someone who know's enough to use a DMM and a soldering-iron, but doesn't have a good grasp of electronics.

It talks a lot about how resistors, capacitors, diodes, etc work.

After that, the useful info you'll get from this book is how to choose suitable components for replacement, voltage-charts and a few basic mods you can do to common amps.

Overall, it's worth the price.

This book is deep enough to explain the subject, but simple enough for almost anyone to understand. I used it to learn about tube amps to repair a friends amp. The trouble shooting charts are very good. It will lead you to the parts or parts that are bad, even if they are expensive.
