It wasn't much fun, and was a lot more time-consuming than I had imagined! On the plus side all of the slide pots now work perfectly with no crackling or jumping.<br>

new foam dust-guard might eventually dry up and disintegrate into tiny brittle pieces like the old one did, but if I can get another 40 years out of it that will see me out! :-)<br>

was closest to the keys before removing them one by one. My only tip to anyone contemplating doing similar to clean out sliders on their own vintage synth would be to exercise caution when using the pliers to fold back the little steel tabs on the bottom
of the potentiometer's case (shown in Adam's article):<br>

point along it's travel. Of course I didn't notice until I'd soldered it back in, so had to remove it and sort that out. It's quite easy to bend the case and even the tiniest bit alters the feel of the slider action.<br>
