IN-14/IN-8-2 Tube variations

Both the IN-14 and IN-8-2 Soviet Nixie tubes have a standard and a fine grid model.

  • IN-14/IN-8-2 Nixie tube differences


    IN-14 and IN-8-2 tubes are both Soviet Military Nixie tubes that have 18mm high digits and wire pins. The differences are the glass envelope shape and the '5' and '4' digits. IN-14's use a upside down and backwards '2' for the '5' digit. IN-8-2 tubes have a narrower '4' digit than the IN-14, but use a normal '5' digit. Note: When socket pins are used on IN-14's the plastic base is not used.

  • IN-14 Nixie tube Standard grid


    Standard grid IN-14 tubes have a course anode grid as shown in the image. The grid is the mesh that is in front of the digits. The standard Large Glass Clock #3 IN-14 uses standard grid tubes.

  • IN-8-2 Nixie tube Standard grid


    Standard grid IN-8-2 tubes have a course anode grid as shown in the image. The grid is the mesh that is in front of the digits. The standard Large Glass Clock #3 IN-8-2 uses standard grid tubes.

  • IN-14 Nixie tube Fine grid


    Optional fine grid IN-14 tubes have a much finer anode grid as shown in the image. The grid is the mesh that is in front of the digits. These tubes are older (1968 - 1972?) and rarer than the standard grid tubes.

  • IN-8-2 Nixie tube Fine grid


    Optional fine grid IN-8-2 tubes have a much finer anode grid as shown in the image (shown with optional blue LED floor lighting). The grid is the mesh that is in front of the digits. The standard Large Glass Clock #3 IN-8-2 uses standard grid tubes. These tubes are older (1968 - 1972?) and rarer than the standard grid tubes.
