George, what are you looking for? A way to remove and replace the potentiometer without removing the front panel?
?
It might be possible, I did it once years ago. Is there a nut between the chassis and front panel? I was able to find a thin 1/2" wrench (A stamped one about 3/32 thick) that could hold the nut. After removing the wires from the pot, and removing any obstacles that prevent rotating the pot, you should be able to unscrew it from the nut by turning the pot body. I'm not familiar with the SX-115 so I can't say if it is possible to do this on it. Holding the nut in place to install the new pot was nigh-on impossible until I cemented the nut to the wrench with two small daubs of rubber cement. It was easy to break the bond once the nut was threaded on. You'll probably have to loosen the nut and play around to where, when the pot is tight against the chassis, the terminals are pointed correctly. After it was done, I think it would have taken less time to remove the front panel (As long as you don't have to do any restringing).

What have you tried in the way of cleaning the pot element? Fader Lube from the same people who make Deoxit is a good product for quieting noisy potentiometers. I think Don was asking what you had tried, if anything?
