I have not been able to figure that out for years. You would think the
internal leads were coated with an insulator so they dont glow, or perhaps
they use a different metal with a higher workfunction than the actual
cathodes, so they would not glow in normal circumstances. But when the

Reporting back on the eBay listing. I received the displays today...hard to
tell whether they're used or not, they fire on all segments OK and there's
none of that 'used' look to the segments that you typically see in well
worn panaplex displays. However, they're a bit dirty and the pins are not

I wouldn’t mind getting SP-101 units. I would like to get them in quantities
of 8, but would rather get all 60 units. Please let me know how much you
would take.
Someone was selling the SP-352 new for $10 each. I bought 48 of those from
him. I can only guess the price would be around that
Burroughs 6844A is domed not flat. I also have some National
Electronics NL-6844A tubes. Frankly, I have had much better
luck with the National Electronics brand. This recently purchased
batch of (8) Burroughs 6844A tubes is a bad batch.
The boxes all are stamped
As an ongoing part of my effort to rationalize my parts inventory with the
likelihood of becoming an actual project, I have a bunch of Panaplex
displays up for grabs. Here is the list:

Do these have dome-tops, or are they flat ?
I have several dead/near-dead Burroughs 5031 and 6844 nixies, which are the
predecessor of the legendary 5092. All of them have dome-tops. I suspect
that the 6844's you have might be the same construction as the 5031. I have
a few of these myself,
I would like to ask the group about an experience I am having with a
batch of (8) Burroughs 6844A nixies just purchased.
They are new in box from 1968. All have same date stamp Mar 4, 1968.
As far as I can tell they have never been out of
these original boxes. I
I might have to clarify: I'm not saying that the IC has a problem and that
I don't recommend it for projects. As I said, it works very well.
The manufacturer itself has set the status to "not recommended for new
designs", they have developed a new version.

Hello.
I was wrong on the leak direction, indeed. I did further experiments with
the couple of tubes that react to the neon tester (HVAC source applied to
one pin, and holding the tube with the other hand).
I could pile up power supplies to just below 700V and digits still don't
light fully.
Or just bad luck. I don't think there is a generic design problem. Usually
and in particular when I have been moving around - I touch some ground
first to discharge myself just to be on the safe side...

The blue ones I have (and looks like yours as well) also show brass in some
places (top and bottom). I have over 100 assorted IV-6 tubes here and to me
it looks like they're supposed to be brass color but some chemical reaction
has turned them blue.

yes, the schematic in the datasheet. I hope it will work as expected, I
already ordered some new boards.

Ah, this is not uncommon. A lot of AVR Dragons were slain for the same
reason. Touching the regulator affects its feedback and therefore its
output voltage. A tiny ESD, not enough to cause any damage, can drive the
output high for enough milliseconds to cook a 3.3V IC downstream.
