The way my XFMR is mounted in the enclosure I can't take a decent photo of
it.  I have asked Guy to provide a photo of his installed xfmr or a photo of
one not yet installed.  When I receive the photos I'll post them on the
page.

An actual pic of this transformer would be worth a thousand words. The
drawings are great but I'd love to see this thing wound and connected for
real. I don't have any experience with such things so having a pic to show
details of how it works when drawings meet reality is priceless.

Thanks for all this, pretty interesting.
