re: still trying to track down a hum...

That resistor on the 12by7 is called a grid stop resistor. It's fine and not your problem.
I have had this type of hum problem before. I used solid 12ga wire from one RCA jack to the other and then grounded the center of the 12ga wire with another length of 12ga wire.
BTW It's good that the coax shield is only grounded at one end.
