ok well I replaced my control pots with "Bourns Potentiometers" mic gain, RF gain and clarifier" because I can wiggle them up and down side to side. The new ones where nice and tight well that was till I took my radio in to have it peaked and tuned.. he sprayed some cleaner in to them and now they are just as bad as my old ones!!! is there a way I can tighten them back up???
