Hello.
Thank you Tomasz and John for the links to neon substitutes. I've tried to
light it up touching what remains of the broken leg but there was no life.
I can tell the bulb was pressed into position and leads forcedly bent.
Your replies inspire me to try troubleshooting a bit further. Voltage
There are three test points in there, two for voltage rails and one
apparently for a time base. I suspect the power is OK if it does power up
at all (unless all the logic chips needed for display do not use it and
have separate voltage rails), what about the 5HZ point?
Also, if the reading is

I wonder if it dried-out. I had the same thing happen to me with a Heathkit
that was 30 years old: small electrolytic cap dried-out, became a

There are a few possibilities:
The Russian IN-3B-1:

I think producers of neon bulbs decided to make searches extra hard
(datasheets with no dimensions or dimensions not tied to bulb name, using
same name for different bulbs etc). But I think I've found something quite
similar in size:
Yep, that was crazy. I only have a slightly used XN-12 from some circuit
board, but it has rather short leads because of that. But at these
prices I am out. ;-) Jens
