One of the students doing a different music course than the one I'm doing, has offered to sell me a Fender Super Twin amp chassis for $300.00, it looks in reasonable condition, except for a missing control knob, and apparently it does work.
I'm going to organize paying him the money for it over the next couple of fortnights, it looks like it could be a good amp restoration project, I'll post a pic of it once I get it home so you can check it out, it is an all valve amp that is apparently capable of putting out 180 watts of audio power
