I bought this book without looking at it in a bookstore. I am a beginner in this field and was looking for something, somewhere that can explain radio restoration techniques to the non-engineer. Unfortunately, except for some interesting historical information, and what I would agree are some useful charts on tubes, etc., this book is written with a lot of electronic theory. Those who already have some knowledge or experience in electronics, or are very technically-minded, might not find that a problem, but the lay person will be tossing it in the air in exasperation after a few chapters. Very thorough but dense.
