This past weekend I was cleaning out the garage and I stumbled upon a friendly relic - my old Randall 1x12 combo, my first 'real' gigging amp. Its as heavy and as loud as a Fender Twin, and (if I remember correctly) it had a really great sound for a solid state amp. Then one day it died. It's been sitting in the garage for almost 20 years now.
It powers up and the preamp still works. I can run the fx send to another amp and everything functions correctly, so whatever got fried only affected the power section. I have a 10 year old now who is all into electronics and I thought it may be a fun project for us to try and figure out what's wrong with it, but I don't know where to start.
If it were a tube amp, I'd roll the rectifier and power tubes, and then maybe look at the OT. But I don't know anything about how SS amps work. Where should I start?
I know someone will chime in with the standard psa about how amps can kill even if they're unplugged. I am aware of the risks involved and certainly won't venture beyond my known limitations, especially with my son at my side. But if there are simple things to check I think i may give it a go.
