hum with VPI Jr

I have returned to analogue recently and bought a VPI Jr with a AQ 7 arm and Benz Glider M2(purchased used here on Audiogon about 6 months ago). I am getting a low pitched hum when I place the cartridge on the record. This hum is not present with the table on unless the the cartridge is actually in contact with the record. The ground wire is connected although I have not checked it for continuity. The table is plugged into to a speed controller. Any advice on eliminating the hum ?

Hi all,
I moved the liner conditioner(speed controller)away from the other components and that eliminated the hum. I did check the connections before I did this and could not move the cables very easily so moving the speed controller seemed the simplest solution. Thanks to all for sharing you wisdom. Don't know what I would do without this site. Len
