Burroughs BD-401 / 6702  
Written by Accutron on 2007-03-25  

The Burroughs BD-401 is specially modified 6700-type beam switching tube, designed to operate as a wide-band noise generator for use in AM/FM radio jammers. The BD-401 has only two functional sets of spade / target structures, with the remaining structures being replaced by anode elements. The anode supply voltage is set for cutoff operation, and the biasing of spades and targets is set to prevent stable states.

Burroughs BD-401 RF noise source, manufactured in 1964.
