text: I've seen better high end audio books. I'm certainly not a member of the aforementioned "Scientific School of Audio System Performance Analysis", the only instruments that can accurately measure sound quality are the ones on either side of your head. I listen to what my ears tell me sounds good, and generally, tubes sound good. Which is why this book is sort of a disappointment, you'd think that out of 80 projects there'd be at least one tube phono preamp, but unfortunately there are no tube amps, just a few rants about how tubes don't produce enough power. Who uses more than a watt anyway? Even the transistor amps presented aren't much better than what you could get from Rex or Circuit City, similar schematics could probably be found on the internet for free. Go ahead and buy it if that's the sort of thing you're into, but if its tubes you want, try Morgan Jones' "Building Valve Amplifiers", it doesn't have many schematics but it covers  in great detail the layout and contruction of tube amps. Good schematics can be found on the intarnub
