Hum...ZYX with Tom Evans Groove Need suggestions

try moving the groove around a bit. it might be catching inteference from the power supply of another component. this happened to my groove plus and my zyx universe. try moving around the interconnects as well.

Thanks for your responses.
Stanwal, yes I have tried cheater plugs. Can you explain more on grounding system to center screw on AC outlet.
I have connect the tonearm ground wire to different places in my system with no improvement.

G_m_c, I have moved the Groove around different locations on my rack and away from the Michell's power supply which did lessen the hum. But it's still louder than what I had with other phonos. It appeared the Groove easily picked up noises from power supplies.

Any other ideas I should try?

have you troubleshot the rest of your system? swap interconnects to see if the left side still has more hum. the ground from your tonearm should ground to the ground lug on the back of the groove. doublecheck all connections, from the catridge on up the chain.. etc. the cartridge/phono pre combo you have are top notch. there is an issue elsewhere, or you have a defective component.

as GMC noted having the power supply in the wrong place will increase the hum. i found that out my self when rearranging my rack. problem solved by moving it around for the quietest location. good luck and enjoy the music
