FM 212R took a face plant and broke the treble pot shaft off. Now the clean channel doesn't work. If I jumper the cap C4 before the pot to the resistor R13 after the pot R10 I get sound. Lifting both shows 48K ohms on the outside legs of pot R10, but open on either side to wiper. That B50K snap in apparently no longer exists, neither does the audio taper version.
So, I ask you, what to do? Should I install a pair of 27K resistors from the wiper to either outside leg to approximate the pot being in the middle? Or 22K?
