I'm pretty sure I played with that control as well, but same as the volume pot on the control speaker nothing changed in the music when I did. I suppose I should try to clean both of them anyway. Electrolytic caps- I wouldn't think this was old enough for those to be a problem, but it could make sense- might have been old stock when they put this thing together.
