Slight hum from VPI HW-19 Motor

Hello All, today while playing my Table, I noticed a slight bit of hum when switching the motor on.

It's not bad, but it is there none the less.
I tried moving the Power cord around, and the hum varied, but didn't go away.

I noted when clasping the Power Cord with my hand, Hum increased 4-fold. Does anyone have some suggestions for a fix? A different AC Cord, some clamp on ferrites? Or?
Ferrites take care of rf. A different power cord will not change it. This is a grounding problem. Are your cables plugged ALL the way in? Is your cartridge wired correctly? Are your cables clean. If you are using a 2 prong power cord, turn it 180 degrees and plug it in again. . Im sure Harry at VPI can give you some suggestions.
