I decided to build a tube what would use the technologie like original nixie tubes. I made a mica sheets, used a glass spacers, build an enclosure for digits with grid.. I also made a new style stem with evacuation tube inside, just as experiment.. The tube could have a round top cap..
The tube ready to bake out and pump down, the vacuum pumps already started and then it happened.. I broke the evacuation pipe 🙁 It is pretty fragile.. So enjoy just some photos of ruined tube 😉
