RCA AR77 - Sensitivity Control Replacement

[ppppenguin]

Linear and reverse audio are 2 different types of pot. As has already been suggested I'd try a 25k linear and see how it works. The modern value of 22k should also be ok. Except in a few specialist applications pot values are rarely critical.

There are ways of simulating non linear pots by connecting a resistor from the wiper to one end.

Obviously it would help to see the schematic.
