I have a GN-4 with an intermittent short between the 0 and 2 cathodes. It goes away when I tap the tube but it comes right back after a few seconds.
This is one of six tubes in a Systron-Donner counter. They're orange coated, no filter in front of them. It's working perfectly otherwise: https://www.astarcloseup.com/2022/04/dawe-3001a-frequency-counter.html <https://www.astarcloseup.com/2022/04/dawe-3001a-frequency-counter.html> Is there anything I can do? Does anybody have one on hand? The coating on them is in great shape.
