Hi Sven,
QEX Jan/Feb 1998 has an article using four microwave oven transformers
to build a HV power supply. Glancing thru I see that a magnetic shunt is
removed from the transformers as these will cause poor regulation.
I'll read it today a see if I can add more info. I recommend you locate the
article.

Hallo!

I am seeking some info about using transformers from microwave ovens in HF
PA power supplies. As one side of the secondary winding is connected to
the
transformer core, I am a bit confused on how to do the voltage doubling.

Any info on the subject is appreciated.
