Hope someone can help me just got a used Sony ps lx 2 turntable. It seems to have a hum runs OK sounds good otherwise. It is definitely grounded to the receiver and it is dd quartz lock. Can anyone shed some light? I have 2 receivers it hums on both of them.

Connecting cables? Perhaps one or both of the shields needs to be crimped a bit, or a break in the cable. Check wires in headshell which can be loose while looking OK.

Thanks for replying so quickly I went down the checklist and just to see what would happen I disconnected the ground wire the humming stopped. I called the hifi shop and the owner told that some Sony tt's went to internal grounding. Go Figure

It's true that in a minority cases, the ground wire need not be connected. Just leave it unconnected, and enjoy the music.
