Any help would be greatly appreciated. What webistes or books etc. can i learn to build my own 5w tube amp to sell eventually? I see if i copy other amps schematics and sell them i can get sued. I am trying to build my own version of the old pignose 7-100 or the dwarf amps but a 5w TUBE AMP instead like a Gibson ga-5. (For my 1st amp I want to try to make a 1 or 2 knob tube amp to minimize wiring.) I have pretty much unlimited 5w 4ohm 6.5 inch speakers. Or I can get different speakers. I have the wood already. Have the ability to get custom made amp knobs. Plan on dovetailing wood models. And tolex the rest. I want to sell these as a hobby.
