I just got a 6909 hi-speed dekatron in the mail, today. I hate hi-speeds, but it was a trade, for a standard speed 6802, so the other guy's spinner would work. But this one is a strange one. My other 6909s and 6910s, have this almost indescribably hideous pinkish/yellowish glow. This one glows almost orange. Not 6802 or GC10B neon orange, but the color of a Japanese DK23 dekatron, with the hint of blue. That's not a problem, because I can look at the lit tube, now, without cringing.
Well it has a strange operational problem. When I stick in my spinner kit spinner, it runs upto a certain cathode, then stops. This is at the preset current ~350uA. If I raise it to ~1mA, the high speeds normal run current, nothing changes. I move it over to my dekatron pendulum jig, and it runs fine, but only at the lower current (~350uA). If I raise it to within its specified operating range, it stalls, at that very same cathode. For now, I'll let it burn-in 24/7 for a few days, at that lower current, and see if it clears up. Will report back later, if anything changes. Plus, I still have to check the issues with those two 6879 dekatrons, I got a few weeks ago, when time permits. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
