Ground loop hum from Turntable

Not sure what is causing this but, i took home a Rega P3-24 to demo, hooked it up to my Plinius 9200 and was getting a loud hum. I noticed Rega does not include a ground wire on there interconnects. My dealer indicated that the ground is done internally. I am limited as to where i can put this table. I have a Billy Bags AV component rack and all my gear is on this rack including my TV. I assume this hum is being picked up from the other components. Any suggestions as to what i can do to greatly reduce or elimiate this hum. Thanks for your input.

System:
Plinius 9200
Naim cdp 5i-2
Speakers Dynaudio Focus 140's & 200c center
Sony dvp 9100es
NAD HT receiver T762
Cables All FMS
TV Sony XBR 960

Cheaters are ok to test for ground loops, but they sound awful. Don't use them as a permanent installation

Cartridge is Rega's Elys-2. It was already installed on the TT.

If your P3-24 has the outboard power supply, try moving the power module as far from the TT as the connecting cord will allow. (That's the hum-avoidance recommendation in the manual that came wilh my P9.)

If practical, you might also try plugging the electrical cord into a separate outlet from the other components.

You mention the TT is near or next to the TV. This might be the culprit. Most newer TV's are always on, even when in the off position and generate EMI which your TT might be picking up. You might try unplugging the TV and see if the hum goes away. Just a thought.
