The CV2271 is a neon filled divide by 10 counter/indicator that can operate at up to 4,000 pulses per second or 2 kHz sine wave. The display moves round the circle via the guide pulses and every 10 pulses an output pulse on c is produced. Commercially this is the GC10B.
The stacked ceramic discs allow all the guides to be connected together.
The central anode with the pins surrounding it. The cathodes are separated by the two guides and by pulsing the guides in sequence the orange glow moves from one cathode to another.
The end window envelope is 28 mm in diameter, and excluding the IO base pins is 84 mm tall.
