  ...invented by Frank H McIntosh in 1949. The McIntosh patent mentions unity coupled OPTs using bifilar and trifilar windings. Corderman references the McIntosh patent in his application.

    Yes
    You are correct..The original circuit was Frank Mcintosh's...I thought I had mentioned Frank Mcintosh but I see I didn't.

    It's a hell of a circuit eh Ken? You have to read it a few times but it falls into place.
