Hi All,

A friend has acquired several Hughes 8781AH Klystron Amplifiers (from
AML-STX-141 transmitters).

The tubes apparently will generate about +45dBm at 12GHz from -2200V,
waveguide is WR75 / WG17 (10-15GHz)

Can anyone help with further information about this tube please.

I am interested in knowing the bandwidth (will it run at 10GHz).

Fire extinguisher and change of underwear are available for the first
powering up...

Thanks,

Mark
