I have a few tube amp books which I have read from here and there, but what they seem to be sorely missing is active involvement, i.e., all theory, no doing. I'm looking at the book by Richard Kuhnel titled, Guitar Amplifier Electronics Circuit Simulation, which uses LTSpice. I have one of Kuhnel's other books titled, Guitar Amplifier Electronics Basic Theory, which I have read on here and there. Two problems that I have with that book are: 1) Instead of starting top down with a less detailed overview of amps and gradually filling in more details as needed, it is all about details every step of the way, which makes for losing the forest for the trees and weeds and is very dry and boring to read. 2) It involves no real hands on projects, which I think is a big part of learning about anything technical. I'm thinking that Circuit Simulation book might be a good way to go in conjunction with continued reading at Rob Robinette's site and elsewhere. What do you think about using LTSPice as something of a n00b tool for learning about amp circuits before getting into actually building something? Of course a simulation is going to ignore lots of real world practical issues, but I'm thinking that it might be a good way for actively getting a hold on concepts before getting into real world issues.
