(Cont. of Point 5 - Badly worn volume sliding pot)

I ordered a small 15ml botle of "Conductive Paint" from Green Stuff World supplier, and used a small brush to apply 5 or 6 layers of paint over the left and right extreme sides near the terminals of the 10KR pot resistor. Did the same all over the cursor strip. We need to be patient on this job, by applying small amounts of thin layers at a time, and waiting at least 15 minutes between paintings. 

The result was better than expected. Audible noise when moving the sliding cursor was virtually eliminated and the sound control is now smooth.
