Haven't got a spare pair of RCAs, but I have tried different cans (the more sensitive, the worse the hum) and just now installed a new opamp. The hum isalmost inaudiblemuch worse now. Put a brand new TI OPA2107AP even though a 2107 was in there already...
The quest continues!
Also, has anyone had to replace any of the screws holding the chassis together? One seems to have wandered off...
I had a ground-hum problem due to the front-right top screw coming loose. This particular screw is a critical component of the ground circuit. So yes, it might well be worth your while to investigate this further...
Good luck!
