Burroughs B9012 Pixie Tube  
Written by AnubisTTP on 2012-01-12  


The B9012 pixie tube, made by Burroughs, is the replacement for the short-lived HB-105 shown above. The B9012 has the same display face as the HB-105 and uses the same obscure double-ring 13 pin base, but has a long life mercury doped fill gas and more refined internal construction. The tube dispenses with the high domed envelope of the HB105 and replaces it with a more conventional envelope that only has a height of 20mm. While still rare, the B9012 is not pure unobtainium like the HB-105, and its long life makes it the obvious choice for any sort of Nixie clock-style electronics project. Variations were made with both blue and black print.

National also made a version of the B9012 neon display. Note the use of blue ink instead of white for the tube's silkscreen print.
