The Burroughs BX-3000 is a high current Beam-X variant, known by only a handful of surviving examples. The BX-3000 may have been used as a microwave frequency noise source in radar jammers, as it was investigated for such use by the US Air Force in 1963. The Westinghouse BX-3000 shown here is particularly unique, because it is the only known example of a re-branded Burroughs beam switching tube.
The Burroughs BX-3001 is a completely undocumented type. The part number is not listed in available Burroughs documentation, and the unit pictured on this site is one of the only known examples. If Burroughs numbering convention is being followed, the BX-3001 should be a variant of the BX-3000.
