Be aware the tube itself is sealed, so even if they were submerged in water they should be fine. Whatever the contaminant is, I can't see any obvious signs of corrosion on the pins.
I see these are IN-1 tubes. *Be warned: They are very unreliable*; see my posting about this from last year for more details. After a few hundred hours of continuous operation I was getting cathodes shorting to eachother inside the tube. It was so bad that my big clock with 15 tubes had a failure every few days. After replacing the IN-1 (NH-1) tubes with Burroughs 6091's, I have not had a single failure. This particular clock has been running for over 9 months now, which means I have accumulated about 100,000 hours of tube-time. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
