I have a TOKHEIM AUTOMATION Motherboard Power Supply ASSY 0443-065 REV E that is installed in one of my Remote Terminal Units and I believe it may be in bad order. I was informed by the RTU manufacturer these units have been discontinued. I have no way of testing this unit to verify if it is in good or bad order. Could you let me know if these power supplies have been discontinued and if so do you have a replacement or can this unit be sent to you for evaluation. Please provide any and all information as soon as possible with repair / replacement cost and shipping. Thanks very much.
