Just wondering if anyone understands the innards of microwave ovens.
The only magnetrons I'm familiar with are the World War II radar
things that have a cathode that takes minutes to heat up and that
run 20 kilovolts or so between cathode and anode.  So how do the
ones in ovens get instant-on, and what kind of voltage to they need?
The units don't seem heavy enough to have a big transformer in there.
