The GC10B is a Dekatron counting tube where the application of a pair of input pulses causes the neon discharge to move around the cathodes in the pin circle. The position of the glow is the readout. At the end of a revolution the tube generates an output pulse to drive another tube. The GC10B can accept pulses up to 4,000 per second.
The ceramic spacers and insulators keep the discharge to the top of the envelope. The guides are all connected in parallel.
The anodes and first and second guides are all made in the same fashion as short vertical pins. The cathode is the central disc.
The end window envelope is 28 mm in diameter, and excluding the IO base pins is 85 mm tall.
