Elesta EZ10

If a dekatron and a pixie tube were fused together in some sort of horrible, The Fly-style matter transporter accident, a nomotron would probably be the result. Nomotrons function on the principles of glow transfer in the same manner as dekatron tubes do, but instead of relying on an external surround to indicate count position, a nomotron has a metal shield inside the tube which directly indicates count through punched or stamped numbers. However, even among the strange world of nomotrons, the EZ10 is unique. With its tiny miniature envelope and 50kHz counting speed, the EZ10 is the the smallest, fastest nomotron currently known. Like the more readily available EZ10A below, the EZ10 has 20 shaped cathodes, an argon fill gas, and a tiny 13 pin base. The pinouts of the EZ10 are somewhat different than the more readily available EZ10A, the guide cathodes are tied into even and odd groups instead of left and right groups, which prevents the tube from operating in a base-5 configuration. Unlike other nomotrons, the tiny mask plate at the top of the tube does not have any number markings.


Elesta EZ10 miniature envelope nomotron.

A nomotron is differentiated from a dekatron by the presence of a cathode masking plate to indicate count position.

The glow position is visible through holes in the top of the plate.

Sometimes the tubes get rowdy when no-one is watching.
