Hum from SAMA

I have a VPI HW19Mk4. There is a noticeable hum from the SAMA .
Any ideas what /how to deal with this?

This is a mechanical hum, not electrical. By that I mean you can feel it in the motor, and I can "hear" it if I press my ear to the table's wooden frame.
I would think this will transfer to the cartridge, or be picked up in some way and outputted through the speakers.
