IN14QC - Spare/Replacement Tube for Nixie Clocks - Kit

* Spare Nixie tubes are reserved solely for our loyal clock customers to assure continued availability. New old stock tubes, with a digit height of .7", an overall tube diameter of .75", and an overall tube height of 2". These tubes provide the classic soft glow of the original Nixie tube. However, the cold cathode for the digit "5" is in reality an upside down "2" cathode. These space-race era Russian manufactured tubes reflect an efficient and cost effective design philosophy from the cold war superpower! Both unexpected, effective, and thought provoking! And a neat conversation starter!
