The new style inverter circuits are a godsend for guys like me with bad
backs. No heavy transformer and capacitor.

Curiously, these ovens use magnetrons that look very much like the old
style versions. The antenna, flanges, housing, connections all look
very familiar.

But what about electrically? Aside from the usual warnings, I'm
interested in knowing if inverter circuits can drive old style
magnetrons, everything else being equal (wattage, antenna height and
shape etc.)

Or is there some fundamental reason why this can't be done. In other
words, what exactly is the difference, if any, between the magnetrons.
