Winding an output transformer for PL36 push pull

[ppppenguin]

Same direction, that'e end of 1 to start of other. It's intuitively obvious that this should be so but I can't quite work out a way of putting it in writing. As for the construction of the winding that's one for Ed Dinning. I worry about putting each half on a separate bobbin because you also want best coupling between the 2 halves.
