Relevant to the recent discussion on the 829 tube, I found an output
amplifier module made by Bendix for the 460 MHz band. It _might_ have
been hacked down to 440 MHz or I might never have got around to that.
I did get around to mounting it in a Bud box with external cables for
power and excitation. It's basically just a box with a cavity with
an 829 in it. I don't remember how it was biased.

The first reasonable offer I get from someone who promises to actually
try to use it will be accepted.
