My Vintage Air control knob for the heater went south, a replacement unit goes for 170$ plus s&h,,,,,I think is high :http://www.summitracing.com/parts/vta-491229/media/images

If you have the Gen II system that control panel is designed for, the heater control is a simple potentiometer. You should be able to get a replacement through Radioshack, or if they don't have a direct replacement through Digikey.
