Thanks John.  Great info.

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.
