I've built most of my nixie clocks around 2003 to 2005. All but one use a dekatron, as a "pendulum". Most of those had the dekatron replaced once. The tube was still functional, but the glass was getting heavily "silvered". Those clocks used a GC10B, or a 6802.
On the other hand, I have 3 dekatron "dohickies" running in my office. One has a DK23, another a GC10A, and the third a GC10B. The ones using the DK23 and GC10A, have been running 24/7 for over 5 years, with no sign of silvering. The GC10B unit has only been running about a year, so its to soon to call. I also have a 6909 running in a simple pendulum circuit, that's been running for close to 8 years, 24/7. The 6909 is a high speed, which are notorious, for being duds. But the glass is this clean on that one ! -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
