No the soldering hole drilling mechanical part isn't too bad. The shematic is growing and taking on a life of its own though. Hard to keep up. I had my heart set on a 2A3 PP amp. This may be beyond my abilities. I know it sounds good too. Without a scope and tech aids to track the circuit behaviour there doesn't seem to be a way to safely follow this. It's a big investment to take a chance on. So; let me ask truthfully; this really isn't a novice project is it?
