I am having the same problems with hum in my system. I've tried lifting the ground, but doesnt work.

"If you can find the offending component then a cheater plug (one with 3 slots on one side and 2 spades on the other side) may do the trick. This happened to me with a turntable, the cheater plug eliminated the hum." -Rfj5106
-was that one component responsible for all the hum in the system? i get hum without any interconnects to my amp...

"Cable TV coaxial lines are notorious for carrying hum into a stereo system. Try disconnecting coax lines and see if this is the source of your hum. A small isolation transformer put in the coaxial cable eliminated this hum."-Rfj5106
-my system is a 2 channel system... does this mean that the coax cable for my cable tv in the other room can cause hum in the ac lines even when my ground is lifted?
