Looking for information on using microwave oven transformers. I have several
of these I wish to use in various projects, some HV some less than 100
volts. I am looking for rewinding information and any modifications that
must be done to the cores.

Be advised that the capacitor goes along with it; transformers i have
seen in microwave s were of the regulating ("sola") type and are good
only for one frequency.

Robert,

I have picked many of these things from the town dump and repaired
them. I've never seen one with a regulating xformer. The oil filled
cap is part of a voltage doubler and also serves to limit the current
to the maggy.

Look at the wiring carefully; the capacitor is directly connected to
the transformer.
The configuration looks just like a "sola" type regulating
transformer; one of the modes is a "constant current" configuration -
and maybe that is what you are talking about.
