I have 14 IN-18 tubes running in my clock for a few years now, with no failures. *They are a good quality tube*.
Be careful when socketing them, because the pin material is a soft metal that bends easily. The light surface corrosion on the pins is harmless, and I dont recommend trying to clean it off. The one exception I've see is an IN-18 manufactured in 1977 that has stiff corrosion-resistant pins. I've never observed any glowing bondwires, or blue dots. Keep an eye out for cathode poisoning, because it has happened to me on a few tubes, BUT it has always been 100% recoverable at nominal current. The cathode poisoning is entirely my fault because the month and year display tubes are basically static. Even though I run a nightly depoisoning sequence for 1 hour, some tubes slowly got poisoned anyways. All I did was swap sockets, and after a few days the problem was gone. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
