Meant to note that the hum does not appear during CD playback.

if the hum only present when the stylus is on the record, this doesn't sound like ground loop, so I wouldn't worry about lifting the ground.
You say you disconnected and reconnected everything - does this include the signal tags to the cartridge connection? If not you may want to try that and apply some deoxit while you're at it.
If that doesn't do it, you may want to see if your cartridge is going bad. Do you have another cartridge to swap out to see if the hum is also there with another cartridge?
Problem solved! Disconnected the 4 cart tags. One of them was not very tight so I took M. Fremer's tip and placed a toothpick in the tag and squeezed it with needle nose pliers. This tightened the connection. Hooked it all back up and the hum is gone. Thanks for your help on this irritating problem.
