I have several with similar darkening, and they are just fine. But, like
Jeff says, it most likely has a few hours on it. It may be fine and then
again, it may not! No way to tell until you get your hands on it. I can
tell you this, most of the 5680's I have that have this sort of darkening
did
Another stepping stone you might consider (although it is completely
backwards) would be a 16-segment VFD based FLW.
I know that I personally would be very interested in such a device,
given the significantly higher VFD availability than B7971. VFD's are
common cathode and are voltage regulated
Many thanks again for the help on this. Somewhat improbably, I now have a
working LED-based prototype on the breadboard - it includes the modes of
the original and a few new ones too. I have multiplexed it for now - to
save space and bits at least - I started out the hard way but then
discovere
Yea i know you can fix cathode poisoning quite easily, but whats with that
dark anode?

remove any oxide buildup (cathode poisoning) from the digits.
They're scarce these days, so handle with care :)

Hi Ron,
it should be non-evaporable getter, based on ZrFe compound.. All nixie uses
some kind of this getter, no one I have ever seen uses a evaporable
(flashed getter) as You use for your experiments. Look on z566m on the back
side - there is another type of non-evaporable getter.
I still owe Yo
Hi Ron,
You got the Account work! Great ;-)
I will check if I find anything about the pellet getter an post here
later (I'm on a business trip)

have not seen that kind of getter and would like to know how it works.
No nixie tube making the last week as I was building my gas charging
manifold and vacuum gauge. It's now all done and the fun be
Don't forget to measure half-wave rectified signals to see what
results you get (square, sine and triangular) as that is something
that many RMS meters fail on.
