Hi group. I acquired an item from eBay with 7 somewhat used Tung-sol Digivac (1x DT-1719A & 6x DT-1704B) https://www.ebay.com/itm/132994915019
Two of the tubes exhibit a strange phenomena - when i touch the glass it fades out for a moment. In general it’s pretty sensitive when i wave a finger around the glass envelope. The filament resistance on the “bad” tubes is close to the other tubes as well (a bit under 10 ohms) I tried swapping the tubes around and the issue follows the tube. Any idea on what’s going on, and if anything can be done to alleviate it? Regards, Per. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
