they work well,, removal of the shunts helps with the regulation
hopefully yours will have the grounded side of the winding
brought out to a terminal where you can open it and
make a full wave supply. The other option is to use 2 matched
transformers that have their windings internally grounded in a
supply that would use a grounded center for the secondary
nice light weight high power transformers
I have used one for my 144 amp for 10 years with no problems
2200 volts at 250 mils or better
the newest Mwave ovens will use switching supply
so get them on big trash pick up day while you can

Hello everyone.
Does any one have experience in using microwave
oven transformers in high voltage power units, I acquired two of these at the
weekend. I was informed that as they stand the voltage regulation is poor, to
improve this the 'Core Shunts' should be removed, (these are laminations
between the two stacks), removal of these 'shunts' also has the effect of
considerably increasing the magnetisation current. The solution to this seems
to be to use two transformers, connecting the both primaries and secondary's
in series to restore the 2KV output voltage.
Any comments on this most welcome
Note for Mal, this is serious stuff not for
appliance operators.
