Great entry level book, and nice for glazing over various maker's designs, mods etc. Short on math & theory though!
I have this book, but it is not dog eared or falling apart yet, so I don't use it much. It is a good book though and a wonderful book for the beginner, or even someone wanting a guide as to "what type of amp should I buy for myself" based upon the various amp tones, high/lo gain, clean dirty, etc. It is short on technical math, & how to use curves to determine gain, & voltages, but an enjoyable read. I cannot fault it for not having tonnes of math. It is a great "paint by numbers" guide to amp design. It took me a few years to get into determinants, & even longer to get into Fouriers, and I still dislike Fouriers. I use a couple times a year, maybe. Better suited for the newcomer than someone who has more experience, but it can also come in handy to have in the library for most people. It is essentially a very good primer to the working of amp stages, tone stacks, & a good section on which amps used what over the years. A little hype ridden, but still cool.I use it more for a reference to who used what where. Most of the different gain stages, tone stacks, PIs etc I knew about when I got the book. I am crazy the old beared guy with a HP48GX RPN programmable scientific calculator & an RCA manual figuring gain, freq response & distortion. I may peek at this book now an again, so it is not worthless by any means, & it is quite well written!
