Hi Otto,
In my expierence all the old Russian neons have quality issues. Of the
INS-1s I have worked with it seems only 1 out of 20 >will glow well for
more than a week. These are far better than the IN-3s tho... out of my
purchase of 500 only 30 or so >worked as well as NOS American-made
counterparts. Perhaps you and I have gotten bad batches or maybe the seals
are >suffering from time...

Wow, what a drag to hear. Are there any similar American made end view
tubes? This clock has to get out the door.
Have you "aged" the INS-1's before use?
Many neon indicators needs to be "aged" properly before use so the ones not
working properly can be removed, you can >read about aging neon indicators
here: http://www.dos4ever.com/ring/ring.html , scroll down to "More on Neon
Tubes" to >read about aging, but read the rest too as it is interresting
reading!
Martin,
No, I didn't. Turns out I did do sorta that yesterday. I discovered I had
swapped the anode and cathode wires, so I switched them back and then ran
'em at about 1mA for 1/2 an hour or so. I read and will re-read the page you
linked, but any guidlines on these tubes? How much current and for how long?
They are at least working again. Thanks!
Jonathan
