As Kwong has already suggested my first idea.....here's another.

Are the signals being transmitted back down one of the leads from the
quadscan.
What happens if the Quadscan is ONLY connected to the PSU ? Still noisy ?

If its in a metal case try attaching an earth lead to the case and the
ground terminal on the amp, assuming it has a ground terminal for a
turntable etc.

If that is OK, reconnect the leads one by one until the noise re-appears.
Try putting ferrite cores on the video leads connected to the Quadscan.

Hope that helps.

Keith

Doesn't this indicate the source of the noise is coming from the Quadscan
unit? If the noise is originating from the PSU, some would be heard even
with no load. As a first shot, try wrapping the power lead to the Quadscan
around a couple of ferrite rings.
