Don, What did you do to supply the +9.6vDC that the backplane requires? I understand that I can use an Astron RM-60M to feed the high current PA connection as well as the regulated 13.8vdc to the backplane and tripler, but how did you derive the +9.6v regulated supply?
Did you build a circuit for it? Has anyone used a simple 9v or 10v regulator circuit derived around a 780x type device? Before I go reading, anyone know what the current requirements are on the Micor station for the +9.6v stages?
