1B59 glow modulator
The 1B59 is an cold-cathode actinic crater glow modulator, on an octal base with just two pins fitted. This was used in fax machines and half-tone scanners.
In the military it was used in the AN/USA-23 Surveillance Recorder Sub Assembly, which was part of the AN/AAS-14 (and A and B) Infrared detecting set (a part of AN/UAS-4).
