Thanks for your reply, Ron.

I did think of using such a transformer. But in the old days I used to
wind power and modulation xmfrs for myself...the iron core for a KW+
capacity would be pretty big/heavy. BUT (idea!) maybe someone has
experience using the new donut cores...and they could possibly be
smaller/lighter for the same capacity?? I don't know very much about
them...

Help ! ? !
