Burroughs B5991 / 8422  
Written by Accutron on 2017-03-21  

Introduced in 1963, the Burroughs B5991 (EIA number 8422) is the ultimate workhorse among all Nixie tubes. Used in countless instruments over a ten year span, the B5991 is a rugged, compact, ultra-long life display in a form-fitting rectangular envelope. The B5991 was second-sourced by both National and Raytheon, and was adopted by Hewlett-Packard for use in their numerous rack-mount timers and counters. To this day, the B5991 remains one of the most commonly available USA-manufactured Nixie tubes.
