Was there ever an updated version of the BC-610. I can remember seeing a Xmtr in a Mars Sta., some place and the Xmtr looked very much like a BC-610 but in an all new cabinet smooth finish paint and in a Battle Ship Gray? color. Cabinet appeared to be steel plate. Clete the 638 finally soaked into my memory and to the other fellow RA-42 Pwr Supply is correct. Stan KG4HUC
