Thanks for the offer, but it won't work for me. I'm looking for what is
basically a choke with high inductance and specially wound for this
application with 30 to 50 H for the classic modified Heising set up in my
new rig as used in many AM broadcast transmitters.

Hmm... and it's got to be nice and broadband. How much DC is going
through there?

I assume the secondary winding off a microwave oven transformer isn't going
to be more than ten henries or so.
