Somehow I seem to remember an early commercial 'radio oven' that used
a klystron; can anyone confirm this?

I was just expressing an opinion. My kitchen microwave is a Panasonic
inverter type.

Please post photos of it together with make and model info; if you
feel frisky, photos of the interior and PCBs would also be helpful
together with a photo of the wiring-diagram label that is often
included.
