To reiterate, there are only 2 things plugged in at the moment. The amp on 1 circuit. The preamp on another circuit. The preamp only has a interconnect running between it and the amp.
When you plugged the amp and preamp into the same duplex receptacle, where you did not have the ground loop hum, did you use the same long interconnects as was used when the equipment was separated plugged into two different power circuits? This is important to establish a common base line to start from.
