Jack, The amplifier is available from Performance Analysis Company, 1345 Oak Ridge Turnpike, Oak Ridge Tennessee 37830. Phone (865) 482-9175. Performance Analysis is the same company that produces the aluminum body for the AutoTemp II servo. A junkyard (try Murray Park at mbpark@xxxxxxxxxx) may also be able to help you.
