Oh, that's a pretty clock! Considering that the tubes hover around $35-$50
each, $240 isn't a bad price.

Numitrons are awesome! Driving them is so much easier than Nixie we all
can relate to that. I especially like the Russian Queen Numitron IV-13 and
also IV-19's because they have the extra segments. The Queens are sweet
though when underlit with blue leds like here:
Some years ago, I made some ornaments using transparent plastic balls with
an IN-18 inside. I did not use any underlight. I made the connections with
ugly gray 12-conductor cables. Somebody in the group gave me the idea to
hide the cables inside colored (green, brown, gold, …) cable sleeves.
... and would a hanging numitron require LED underlight - which would in
fact be an LED overlight?

Well, that's an interesting idea - and with some code adjustment - hanging
numitrons would work just fine.
I suspect that ribbon cable might not be the connection of choice as you
might want to match the tree decor, some bundle of green/dark wires might
need to be utilised.
In which case -
Well, it's December soon, my favorite application for remote
nixies/numitrons is making ornaments (balls) and hang them on the tree. A
4-digit clock in the tree looks very nice.

Yes, indeed I could do that - it would make the board a lot simpler though
my regular train of thought is that I have to mount the tubes somehow so I
might as well make it a single board to save all that wiring and space etc.
If there was ever a situation where remotely mounted tubes was a
hae you consider putting in rows of holes for pin headers so you could use
it for remote tube sockets ?

Ah, OK, I can see what you did there - excellent.
and you can see that I did mostly the same, I just modified the
circuit board to fit the tubes - same software!

I'm about to embark on a similar journey - I've gone for tighter tube
spacing which I'm not 100% convinced will be right - time will tell.

Subject: Re: [neonixie-l] Re: Looking for some info about RCA DTF numitrons
Would anyone care to sell me an end view Numitron (DTF104B) to add to my
vintage digital working display?
I would also like a DIP 7 segment incandescent display, or anything interesting
not in the picture. Nothing too
It counts on the digital displays, scrolls text on an LED display, shows
characters on the LED Matrix between scrolling through all 64 dots.
CRTs were one of the earliest displays so I used a CRT clock kit bought on
Ebay.
If anyone is interested I can send illustrated notes with schematics

That looks really nice, what does it do? If you’re interested in minitrons, you
can find them in used avionic equipment.

I'm glad to hear that - it means that there will be other projects showing
up with them. One of the reasons I like Numitrons so much, besides being
incredibly easy to drive, is their longevity. At rated voltage (which I
don't
I'd say that they are pre-production or engineering samples, tubes that are
produced either for in house development or samples sent to presumptive
buyers/customers who are interested in designing with them to release
products as they become available in production volumes.

Thank you Martin!
What does it mean in practice? Are those just an old names of the same
tubes, nowadays named DR22xx?
Sorry for banal question. I understand the words, but not the whole phrase.
Mark, those are beautifull, I won't be able to sleep now ;)

I have a pretty good sized collection of RCA DTF-104B Numitrons, which I
think are especially attractive - they're large digits, in a flat-topped
end-view tube. They're quite rare now, and in fact I think I have most of
the remaining world stock of these things (around 150 or so). Although
I knew I'd seen the number, and found them just now:
http://www.tube-tester.com/sites/nixie/dat_arch/Numitron_RCA_01.pdf at the
bottom of the page, they are development numbers for the DR2200 series.

Tubes designated DTF are development numbers used by Apollo/RCA - it says
so at the bottom of their datasheets.
