Nice to see a new design! Many many years ago i scoured patents and books for Dekatrons and other counting tubes and I have a very faint memory of a similar design in a Russian patent application. Maybe our Dekatron Guru Jon does have information on this one?
Any chance you can set it up to run and record a video to show us all? /Martin On Saturday, 22 November 2025 at 19:29:27 UTC+1 Greg S wrote: > Hi! > Do anyone know this type of dekatron?
