Thanks for sharing your knowledge with me, everyone!I'm learning a lot here, it's very interesting! Getter :It's funny : Just yesterday I saw a photo of the getter activation on Dalibor's Facebook page! Ageing / testing :Ok, so it is in fact almost impossible to tell the difference between a NOS tube and a lightly used one.In the future I will simply inspect the glass in front of the numerals and if the sputtering is acceptable the tube will be ok for me. Deposit on the side :Even though mercury seems to be the main culprit, I think the sputtering from the wires, as mentioned above by Martin, can also be the cause in some cases.I have an old Z560M where the wire illuminates as well as the numeral (for all the numerals) : the sides, where the wires are near the glass, are completely "silvered"!Below is an example with and one without the deposit : <https://lh3.googleusercontent.com/-smgy1dyNUhI/VuyTAkvBwsI/AAAAAAAAAmw/JcAIWo-MJqYUemiY5eeoCNDZV991PpNfg/s1600/IMG_0016.jpg> <https://lh3.googleusercontent.com/-91gQZuG_qbE/VuySlD6Z6SI/AAAAAAAAAms/7UY7TZ-5j3QJD1E4vuW2i-VvLRWPFHvPA/s1600/IMG_0014.jpg>
On other tubes I have a grey film on the glass following exactly the wires close to it. Concerning the mercury in IN-12 tubes, is this what you can see in the photo below? <https://lh3.googleusercontent.com/-DrHbKvj25V0/VuyVDEVh3nI/AAAAAAAAAnA/TpJFU3Tx36kLqzJbBWC4fGbAvbUN7UfRw/s1600/IMG_0013.jpg> Is the round thing in the middle the mercury pill? All 6 tubes I have from that batch show a thicker film in exactly the same spot (whitish in the photo, but it's reflecting). Have a nice week-end, Alic -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
