I would also measure both sides of the new resistor when the sound goes bad to see if the currant has gone up.
If the currant is going up something is taking enough currant to starve the preamp of power.
It looks like there is a 3 pin screened cable plugged into the PA board. Try unplugging it and feed a signal into the PA there and see if it still sounds bad.
