Hum from SAMA


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

Remove belt and put some oil on the shaft. It will seep into the motor and should take care of the noise, then wipe clean.
also...if the feet are rubber and old, they should be replaced with new ones easily procured from VPI...aged rubber feet turn hard and transmit what sounds like hum through the cartridge.
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.
Thoughts??
