Default AV123 sub amp hum???? Hmmmm....

I've got a ULW that had the factory refurbished substitute 500W sub amp from AV123. There is a low hum at times, but not always. Seems to be there when the amp has been on continuously for many hours, but can intensify with actual use for music.

Any ideas?

It is more like a tranny buzz than a heavy duty ground loop hum (I know what those sound like and have all units grounded to the same point.)
