I have the same problem. About -50dB ground hum idle. And it's changing with the volume pot: if the volume is at zero, there is no hum.
Replaced the supply, checked cables, and solder pads... everything seems fine. Although, I tried it yet only with breadboard, and jumper cables. It's not boxed yet. And in some cases, male + female cables are connected, so it's maybe just the poor quality, because when I changed the way/place of grounding, the loudness of hum changed, the lowest was -50dB, the highest about -40dB.
I think, I have to switch to direct, real wire soldering, not jumper cables and headers.
Any idea about this? As I see, this case is not solved, and closed, have You find a solution?

Thanks,
regards

Anybody ever messed with one of these before?  Just picked one up for $15 at a Goodwill, first I've ever seen.  Didn't get to test it because the adaptor jack pin was bent and wouldn't accept the only negative center adaptor I could find there, hopefully somebody didn't screw up and put the wrong polarity to it and fry it.  Guess I am buying some batteries tonight.  It's a 100 voice PCM keyboard, doesn't look too fancy, though the "one finger ad-lib" looks interesting, some kind of arpeggiator or accompaniment I guess, hoping I can find a way to add separate volumes for rhythm, ad lib, and main voice.  Not a lot of info out there, any pointers appreciated.
