Obviously it is a grounding issue related to the "upgrade". The chassis either has a bad ground to signal ground or too many grounds. Try taking a wire and touching it to the chassis and the other end to another component. What you may find is that the RCA grounds have been messed with.
The dude who designed the component was pretty bright, probably a lot brighter that Mr. Greenstreet, or whatever.
Could be the unit is picking up AC hum from house wiring. Outlet grounded properly? Polarity of house wiring (Hot, Neutral) consistent?
Are the input wiring of the amp shielded? Grounded at input side, only?
Check all grounding points within the unit. Tight and clean. With least amount of potential between grounding points. Near zero resistance between points of grounding.
