still oscillating, 180 phase reverse from fb wind at 120 kHz with this latest wind,
so we add screens and go back to pri-fb-sec coil struture,
that way we only need two screens, with sec-pri-fb-pri-sec we need 4 screens, not enuff room for the extra tape and wire screens,
but wait, why not make one last ditch effort to avoid screens by using reverse winding?
lot's of permutations, rev wind pri, rev wind pri and sec, rev wind pri and fb, rev wind sec and fb, rev wind pri , sec and fb, rev wind fb, rev wind sec,
6 ways to win, start with the easiest first, rev wind fb,
going to keep the sec-pri-fb-pri-sec stucture as sq wave ringing was dramatically reduced over the pri-fb-sec structure,
