TT grounding issue


Had a steady hum through my tube system. Finally pinpoint it to ground wire from TT.When ground wire is removed from grounding peg on the phone stage the hum is gone.The sound stage just opens up, beautifully quiet. Is there any problem running the TT this way??

It's probably already grounded somehow, (most likely through the interconnects). By adding the ground from the table you are creating a ground loop. Leave it off, no problem. You might put a piece of tape on the end of the wire so that it doesn't touch anything and short out a component.
