Thank you very much for your comprehensive replies, I think you have offered every possible angle that I could possibly see. I believe the hiss to be source induced, and the hum mostly is a result from the power transformer being in close proximity to the output transformers. The only thing left would be for me to follow your advice and attach a dummy load to the source end, to see how much the cables introduce into the system. I will try to research some different grounding schemes, I do have a BPT power strip that has a star grounding scheme for all its outlets, that might help determine the problem. But the amp itself is practically dead quiet, which I am happy about.
