I found a replacement 5K pot with switch at <http://www.mouser.com/>.
The Mouser part number is 315-2415F-5K. The switch is SPDT so
it can be wired for whichever configuration you need. HTH.
Cheers,
Rich Schmidt

Now, under load or not the speed randomly jumps up to roughly twice the set speed. I can't afford to replace the controller now. Help! Is this the symptom of a fet going bad? I do believe I have some spares.
