If it's a simple switch + potentiometer you may be able to measure resistance at several points and find a replacement at Mouser or somewhere like that. If it's just a dirty pot, you may be able to use some cleaner on it and get a few more years out of the existing one. Good luck, Craig

We have some measurements but the number appear high (I am not a electronic guy) and were hoping to get actual specs before we looked around for a replacement.
