I would like to build my own hand-wired tube amp, however I know absolutely nothing about electrical theory. I've made my own cables, aand soldered in a few true-bypass switches before, but that's about the extent of my experience. I know I won't be putting the final touches on my 3 channel plexi by this weekend, but where do I start? What are the critical books that I need to read? Where do I learn the details of transistors, pots, & tubes? Thanks!
