Re: [neonixie-l] Re: An investigation into better ways to do cathode poisoning prevention - 1000 fps slow motion included

The '4' in the unit-hours position I saw in the video should not have been poisoned during normal operation, because all 10 cathodes will get exercised. Could this tube have been in a different position, such as the 'tens hours', and been poisoned that way ? What I'm wondering is if this is

Oh btw, the tubes had about 16K hours on them 3 years ago. In the new clock they're on for 15 hours a day, for 3 years.. is another 16K hours, so they have about 32K hours on them. Kiran On Wednesday, April 11, 2018 at 1:58:51 PM UTC-4, Kiran Otter wrote: > > While I don't mind the

While I don't mind the slot-machine effect, I don't know how effective it is. My tubes only had slight poisoning when I built the Spectrum 18 clock 3 years ago, and now several have developed problems. Here's a video . I slowed it
