Alan,

Thank you for your advice.

First, the noise exists without any video hooked up to the system. The noise exists when only the amp and pre are attached together before I get a chance to attach any other peripherals.

The pre amp does have a head phone jack and with nothing attached to the pre amp besides the power cable and the head phones I have noise. It sounds similar to the humm from the speakers but not quite as intense. It is independent of the volume control, however if I turn the volume right off then all noise goes away, if I turn it up all the way the humm stays but is mixed in with a good amount of white noise.

So does this definitively mean that the pre is bad? I will be calling for the location of the nearest service center tomorrow.

Thank you very much!!
