Humming?

Hello, I have a Music Hall MMF5.1 going into a Creek OBH-18 phono pre-amp. The thing is, I have a very audible humming noise coming out of my speakers. I am pretty sure it's my turntable to pre-amp connection as as soon as I disconnect the power supply to the turntable, the humming disapears. I have a grounding wire connected from the turntable to the pre-amp, and if I move the grounding wire around, the humming varies in intensity (from almost gone to loud)... Can somebody tell me what needs to be done to get rid of this problem? Thanks.

Thanks for the help gents.. I have the stock Goldring 1012GX cartridge that came with my MMF5.1. I grounded my turntable by connecting the grounding wire from the turntable ground connector to my phono preamp ground connector. The humming doesn't stop when I turn off the turntable, but it stops when I unplug the turntable's dc adapter.

How do I ground my phono preamp? Connect the ground connector to the amp chasis?

Thanks again..

I meant the grouding connector on the back of the turntable in between the rca connectors... The MMF5.1 came with a RCA cable that has the groud wire attached..
