Williams 150 Watt Transformer - looking for schematic for control unit

KMKOGR Forum Member

Does anyone have a schematic for the control unit of the Williams 150 watt transformer they could post, or know where one is available? I am referring to the old unit with the very large separate transformer that plugs into a very small control box that handles all functions. It was the immediate predecessor the 80 watt Atlas/Williams units.
