Your problem may not be your tumbler. Have you checked you electrical supply? Is the outlet your using supplying 120V+ to your tumbler? Does your voltage drop when a large electrical load kicks in? (furnace starting, water heater cycling, wife using oven, or excessive load on the 120V circuit you are using for your tumbler) Check your electrical supply with a VOM and verify you have 120V+.
