So I'm trying to set some builds so I can fill up my bench and I'd like to try a 71A. As simple as it can get is preferable, since I strongly believe in the K.I.S.S. When I google a SE 71A schematic 2A3/45 comes up a lot, I am no electrical engineer but I do have tube amp builds under my belt . I'll read and study a build for 6 months sometimes before I build so I know whats ahead of me and to get to know the circuit. Thank you and much appreciated
