Delta grinder speed control

Don A. Davis
My Delta variable speed grinder (GR 450)(5 amp) has stopped being variable speed. It only wants to run flat out. I like it slower. I'm thinking a new pot. Radio Shack has 5k, 10k and 1m pots. I have no idea what to get. The manual isn't helpful. The sites for Delta parts show the speed controller to be obsolete and not available. It's probably a long shot to fix but I would like to give it a try before buying a new grinder. Any ideas would be appreciated.
