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 working face: in operation an orange glow appears at the main electrode that is in use.
The wide glass tube envelope is 29 mm in diameter, and excluding the IO base pins is 87 mm tall.
References: Datasheet. Type CV2271 was first introduced in 1952.
