AC Hum problem

It is most likely a ground loop.
Getting rid of can be simple or a real pain.
Easiest solution is to plug everything in exactly the way it was
before (no hum).
This includes how the components are plugged into the AC outlets.
Sometimes flipping the plug 180 degrees (if possible) will do it.
