Just got the pro-ject debut carbon. I have a bad hum. Its not motor hum, it hums even when the turntable is unplugged. I have grounded to the amp(Denon AVR-2802). Have tried plugging amp and table into same outlet. The only way I can change the amount of hum is if I touch the back side of the cartridge. That makes it 3 times as loud. My last turntable didnt do this. Any advice before I return this unit?
Thanks for the help!
