i opened it up, removed the board, and found a wire that the solder joint at both ends was cracked i think this was an earth for one of the pots, but I forgot to confirm this), and another wire with one end that had a cracked joint, and the wire was wiggling in the PCB hole.
after re soldering those, and using some contact cleaner in all the pots and worked them back and forth a lot, everything works fine...
i thought I'd post what I found in case anyone else ever has a similar issue.
when I looked at all the capacitors, none of them showed any signs of overheating or bulging, and no resistors showed any signs of burning out like you sometimes get in tube amps.
Cheers
