I hope this answers your question. Are you asking about a specific amp or any one of hs designs? He has a few books published with several versions of high and low power amps scattered about the book.

I built a small 12 watt version that was described in his book "Electricity and Electronics". It uses a LTP as the input stage and TIP 31 and 32 power transistors as the output stage. It sounded OK. It oscillated the first time I set it up, but I fixed it by shielding the input. I even built a lower power version using 2n4920 and 2n4923 transistors as the output stage and it actually sounded better.

I donít have any sophisticated test equipment (just a multimeter), so my assessment of it is based on my ears and subjective comparisons to commercial amps. I built it to use for a guitar, and also tested it with a Walkman type CD player as a musical signal source. (Can't check voltage and current while playig a guitar...)

Regards

It Was The Book High Power Audio Amp Construction Manual
I Was Thinking About Building The Design 3 11.4 Or Design 6
11.8 But I Would Like To Get 200 Watts Rms 8 Ohm.

I Also Looked Into A Chipamp ,But It Looks Harder To Build
Than A Class B

I donít own that book, but was thinking of getting it. There were a few reviews on Amazon.com that said the book was full of errors. (Though who knows if they were qualified to decide that point). Have you read it, and is it a good book? Iím looking to expand my knowledge of audio, and the book sounded good, but I donít want to build projects if itís full of mistakes.

Sorry, I don't know any books on those subjects. Rod Elliots site (ESP sound products) has some good info on preamps (but you probably already know that) but I donít know any about DYI CD players. The magazine Nuts and Volts had an article on a DYI MP3 player in the fall of last year - it was a project, but no much about the theory.

Thanks for the info. I might get the book.

It's an interesting book, but you do have to watch out, there's at least one design that "looks" good but doesn't seem to have been verified to even work. There's a thread on this forum about it...

Cheers
