For each of my expensive tubes (b7971, R|z568m) I measure and plot the I-V characteristics. There aren't any serial numbers on b7971's so I just write one on the backside.
If the tube fails later on, I check the I-V characteristics to see if anything changes; so far only 1 b7971 has failed when segments shorted together. None of the unaffected segments showed any measurable changes. I definitely need to add the runtime datalogging. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
