Humming?

Here is an easy idea. Try adding a ground wire from your preamp to ground.

What cartridge are you using (some carts such as Grado are especially susceptible to hum)? When you say you have a ground wire connected from the turntable to the phono preamp, where is it connected at the turntable end? Do you also have a ground wire running from the tonearm to the Creek? Is there a ground connection on your preamp to which you can run a ground from the Creek to the preamp? Hum problems can be very tricky to solve (as you're finding out). You might try starting from scratch with NO ground wires connected and then add one at a time, in various combinations. Sometimes it works best to leave ground wires DISconnected. Good luck, Dave

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..

When you say "turntable ground connector," is this part of the connection from the tonearm or from the turntable itself. You do have a ground wire coming from the tonearm, don't you?

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..
