Yes, that switch is wired correctly. While you are waiting for a new switch, it gives you time to fix the other wiring.

I'm still unclear as to R 1 & 3. What wiring is in need of fixing?Yes, that switch is wired correctly. While you are waiting for a new switch, it gives you time to fix the other wiring.
Thanks, but yeah, I checked all the voltages. Also, the damn thing worked just fine for a long time. This is new. It's improved since I cleaned the pot, but it didn't go away. And when I put the pot back together, still off the board, I checked it with a meter, and it was doing weird stuff. The ohms would go down nicely and proportionately, but when it hit the stop it would jump back up 10ohms. I thought about just replacing it then, but went ahead and put it together to see if it was fixed. But no new parts have been added, or changes made. It ran fine for more than a year, then sat for a year, protected, until yesterday.I'd also download the data sheet for the original opamps to see what the maximum voltage spec is and what the pin outs are. Then check voltage at those supply pins. Usually marked Vcc+ and Vcc- if I remember correctly.
