I remember back in the 70's we had radar sets with ZERO volts on the

I haven't done anything with radar in well over 30 years, so I don't
know if they still do it or not. But I wouldn't be surprised. At first
glance it sounds crazy - but it made for a very simple and efficient way
to couple the output of the magnetron to the waveguide.

Microwave ovens still do that. At least, my Toshiba does.


Probably. Although I could kick myself. In the last 4 years I threw
away two microwaves - an 1100W one and a 1300W one (both had control
boards fail). It wasn't until later I thought about taking them apart
and using the power supply for a homebrew amplifier.

Not going to do that again!
