[Boatanchors] frozen potentiometer

[Jack]

Hi Steve,

I have had Kroil work when the others have not. Suggest you get a can on order as a fall back position. A small pint can will probably last for as long I will.

The pot. isn't stuck on the range switch shaft. I can't use a hammer until I remove the potentiometer, because of the spring clip. Maybe things will start to move when the spring clip isn't pulling on the pot. shaft. I'll pick up some Blaster PB and go back at it tonight.
