I am not a fan of how this book is structured for the amp stuff, opens up with an analogy to JFETs for the "solid state experts," really should start out with how tubes work and build off of that instead of something many would not get. But it does cover everything you need, just does it in a sort of roundabout way that is not great for learning.<p>Part one of the less popular and much more brief third edition of the Radiotron Designers Handbook [0] is probably my favorite writeup but is very dense and covers a good deal of stuff in those ~80 pages. Aiken Amps White Papers [1] is pretty good and the first amplifier I designed (and built) was completely done through those pages, still have that amp and have sold it twice and bought it back twice. The Valve Wizard's writeup on common cathode gain stages [2] is also quite good and I would have bought his books based off it if I had not found them right when I was leaving this stuff behind.<p>0. <a href="https://archive.org/details/radiotrondesigne00unse/mode/2up" rel="nofollow">https://archive.org/details/radiotrondesigne00unse/mode/2up</a>
