I scored a SS Fender Frontman 212R for £50 (it actually works and has no issues other than it sounds like a SS amp). So now I have a summer project to convert it to a tube amp, the electronics should be straight forward. I'll wind the transformers and a choke. To keep the budget low I'll use old USSR clones of 12au7/12at7/12ax7 (I already have a bunch I got for £1 each) I also have 2 of the USSR 6L6 clones 63pS, maybe good for a 40 watter. I'll reuse the spring line but drive it from a constant current tube circuit. I'm thinking it will take a lot of lipstick on this pig to get it to look like a Twin Reverb though. A lot of work on the faceplate and it's missing a knob.
