Hi Jim

I saw this circuit on 2 different books one is a 400 page book about
industrial power supply and
it's show with only one transfo without a center tap on the transfo. I need
to test your way to
do it, because it could be a way to ground the primary circuit  using 2
symetric primary coil
ground at there jonction.
