Hi Mike,

Yes, the problem seems to have been fixed long term. The pins in question on
IC503 where I installed the 100k resistors to ground were the noninverting
pins, #3 and #5.

Good luck.

Hi David. I know this thread is a bit old. How do you solder the 100k resistor to noninverting pins #3 and #5? Do you happen to have a picture of the actual solder of the resistor? Also on the resistor, what watt is the resistor? Thanks!
