Great find ! Working high speed Ericsson dekatrons are next to impossible to find. The GS10D has the same pinout as the slower GS10C, and 6476/6476A. Also the GS10C is designed to operate at lower currents, but it may work, if you can reduce the clock rate. For short term operation, running the GS10C over its design limits does no permanent damage. Something to consider, until a working GS10D shows up.
An excessive portion of high speed dekatrons are found to be duds. Usually no gas, to ionize. This rarely happens with standard speed (neon gas / orange) dekatrons. The gas in the high speed tubes, I believe is either hydrogen or helium. Blue/violet glow is not unique to argon, as some assume. If the gas is helium, it can diffuse right thru glass. If its hydrogen, it can bond with the tube's metal structures. In either case, over time, tubes with these gases will go bad, just by sitting on the shelf. And these tubes have not been made in decades. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
