Can I ground my preamp?

I have monoblocs each w/their own grounded cord and a preamp w/o a grounded cord. The problem is that I'm getting a slight ground hum from each amp. The amp manual says if this happens to use a cheater plug on the amps and to ground "at least one other component." Is it possible to ground my preamp, and if so how? Many thanks for any advice.

Hey Stanwal,

Thanks for this advice, and I will definitely try this.

Wow, this is more complicated than I thought. I think I will try your suggestion first, Stingreen, to see. BTW, the amps are the only grounded components (CD, DVD, and preamp are all non-grounded). Am on work travel, but I'll report back when I get a chance.

Quick update here: I lifted the ground on each amp via cheater plugs and voila...hum gone. Thanks for all the advice, and I've learned quite a bit.
