Grados are known to cause a slight hum on certain tables. (Check the sticky at the top of the section.)
Does the hum mostly occur as the stylus gets close to the end of the side? Is the hum in both channels, or just one? Does it get louder if you touch the tonearm or headshell?

Yeah, one. Buy, beg or borrow another cartridge - Shure, Audio Technica, something not Grado, install it, and see if the hum goes away. The Grado (Prestige line anyway) is sensitive to AC nearby.

beatcomber,
I saw the sticky, but without knowing for sure which cartridge, it didn't help me much. The hum can occur with the tonearm just sitting at rest, doesn't seem to happen any more or any less as stylus gets close to end of side, is in both channels, and can be started if the arm or headshell is touched. I don't remember if it gets louder or not. (am away from system at present)
Hilltroll67,
there is AC nearby, but not super close, so I didn't think this was the cause, though a TV 5' away does seem to affect it.
Thanks for pointing me in a direction to start.

Sounds like a grounding issue with the turntable or cartridge.

Before changing or trowing your cartridge away, first check the small things.
One, are the TT interconnects touching or crisscrossing other cable, especially the plug in cable. Second, have you tried to move the TT in a different location, away from other component or maybe closer to others component, (different place). Third, is your TT grounded to your receiver or pre-amp, if it is, try the ground wire at a different location, or try to ground your receiver at a different location. Sometime when equipment are grounded to each other, you may have a ground loop.
