Hi Todd,
Sorry, I don't see a clear view of Resistor 77. You may have to (gulp) move some of the wires. The leftmost of the 3 caps in the 2nd pic appears to have the + lead to the cathode of th rectifier. this is correct. R77 is very buried. The negative of this cap should go to the 4th terminal from the left of thos resistor, joined with a lead from the transformer HV secondary. If not so, this may be the cause of the hum. Also, ensure that the wire from terminal 2 is not touching terminal 1 (ground.
Unfortunately, you are dealing with a rubber wire nightmare here.
Will try to get back on tonight or tomorrow, gotta go to church.
