Nixie ·Nixie
Bidirectional ten-way cold-cathode counter/selector Dekatron. A transferable glow discharge steps among ten positions in either direction, allowing the tube to perform electronic counting, sequencing, and selection rather than serving only as a visual indicator.
GCA10G is a bi-directional 10-way counter/selector Dekatron, classified as Nixie for this batch. The supplied datasheet describes its cold-cathode discharge operation and published electrical ratings/operating conditions.
