Anyone have a 500K linear taper multi-turn (3 or 5 turn) panel mount 1/4" shaft pot they would like to trade some $ for? The shaft needs to be long enough to hold a knob. I can cut short if necessary. Anyone know of a source for such a pot? I tried the usual sources (Mouser, Digikey, Newark, Allied). It's for my Sprague TO-6A. Thanks, Ken
