Volume control "pops"? Usually just dirty. DeOxit from Caig is great for pots and jacks. I prefer to use the blue for moving parts and red for contacts. It is possible you have an IC issue, but that symptom is usually similar to a dirty pot. You get static no matter how many times you clean. Caused by DC on the pot. Pops could also be caused by a circuit failure. Bad power, bad coupling cap or bad IC. Try the spray! Most electronic places like Digi-Key or Mouser sell the Caig line. If you do need to replace the pot. You'll need to know the value in ohms and the taper type. Log, reverse log, audio, and linear are the most common taper types. The ohm value will almost certainly be in Kilo ohms. 10K, 50K, 100K, 250K, 500K and 1Meg pots are the most common. Because the voltage level is small, you'll probably be dealing with a 1/4 or 1/2 watt pot. 1 watt and 2 watt pots are much larger and probably won't fit physically. I suspect the pots are PCB mounted as this is the most economical manufacturing process. If you are unable to locate the proper PCB pot, you could wire in a replacement. If you need details on how to do this, please feel free to contact me.
