Unsolder that treble pot from the board and confirm that all 3 legs test ok and are not open.
Next look at the pc1500 schematic in this sites tech section and then pull out transistor q1521 and q1522 and prove out those.
I do not really see any electrolytic caps in that part of the circuit that will make for you issue you are having with that channel!
