Turntable Hummmm

When the stylus hits the vinyl?
My wild guess is the cartridge cantilever is bent or cracked and vibrating. Why not remove it and take it to your local, friendly audio shop? If you have another cart, try that one for comparison.
Good luck. Keep us posted.

Problem solved! Disconnected the 4 cart tags. One of them was not very tight so I took M. Fremer's tip and placed a toothpick in the tag and squeezed it with needle nose pliers. This tightened the connection. Hooked it all back up and the hum is gone. Thanks for your help on this irritating problem.

YES!!!
