Looking at the schematic there should be a decent DC voltage across the pot track when tuned to an FM signal and less so when the receiver is switched to AM and tuned to a signal. Is C48 (Trader sheet ref.) ok ? As that would form a DC path from the pot slider to ground via R27 if it was leaking and could in theory result in a noisy pot depending on how leaky it was.
