I found this link for a 2700v 1a supply using microwave transformers.

The light Panasonic ovens that say something like Inverter on the logo are switchers. No heavy transformer anymore. They provide negative polarity hot and operate in a current limit mode, not voltage regulation. There is a website on them, if you search for it, that talks about dissection of one, and the test results. They are pretty neat power supplies, providing like 1/2 amp of DC at >2kV. But very dangerous to play around with, unless you isolate, isolate, isolate. If you do decide to pass on the power supply, I would love to have one to play around with sometime. Might eventually be reconfigured to make a nice tube power supply. John K5PRO
