4.0 out of 5 stars A Helpful Introduction to AM Valve Radio Repair, 26 Aug. 2013
Verified Purchase(What is this?)
You will probably find this book most helpful of you are beginning to take an interest in valve radios, and want to find out more about their history, principles of operation and repair. The focus is on AM Superhet design and repair, and Carr takes you from basic valve theory, through the various components, and on to actual circuits. He covers each stage from RF amp through to AF amp and power supply, with examples of typical schematics. His style is easy to follow, and he doesn't get bogged down in detail. There are a couple of interesting chapters on the dangers of electrocution, and on repairing water-damaged sets.
However, note the following caveats:
The book was printed in 1991, so some details are dated, such as the section on test equipment .
It is written from an American point of view. The principles are the same, but the valves used, circuit voltages, and the names of manufacturers are different.
There is nothing about FM circuit architectures, although the alignment of FM sets is covered.
The cover blurb bizarrely does not accurately describe the contents. It says this is a book about restoration and repair. There is nothing about restoration. Also, it claims to be a complete guide to restoring transistor radios. There is virtually nothing about transistors in the book, except in the section on alignment.
The author clearly did not read the manuscript after it was typed up (he thanks friends for having done this). There are many mistakes, especially in formulae and sometimes in the text, which betray that those friends do not share Carr's technical knowledge.

All in all a worthwhile purchase, if a little pricey. Sometimes you may wish that there was a fuller treatment of some topics, but this book will prime you for the considerable number of very helpful websites on valve radio repair. You might just venture to attempt a repair with Carr's volume open beside you!

4.0 out of 5 stars Pretty good., 12 Nov. 2014
Verified Purchase(What is this?)
This review is from: Old Time Radios! Restoration and Repair (Kindle Edition)
Plenty of useful content including lots of examples of circuit design and procedures for refurbishing old radios. Would have given five stars except for two things: strong US bias not made clear in the product description, and a surprising number of typos and grammatical goofs. I'd be amazed if the script had ever gone near a proof reader.

This book meets my requirements. It is a nice addition to my valve technology library which is a dying art.
