Hi, Good evaluation. Now I won't have to buy it. I read number 4 and after a while felt that much of the information was dated. I do think that it is a worthwhile thing for someone new to audio to read though. A lot of information is useful. Funny thing is I don't use 6SN7s as they are noisier than other tubes I use and I do use LM317s in "Odd" circuits. PSpice? What's that? Something you put on food? Just kidding. It is useful in establishing starting points in tube designs. From there is usually has to go the hard way with testing and evaluation to get things to really work like you want. Good write up.
