Hi,
yeah, I really should add a manufacturer category. The problem is that
this whole thing is still a static HTML layout and for sorting options I
would need to add PHP in order to make it a little bit more practical
for me. We will see... ;-)
And I admit, I have been very slow in uploading new Nixie tubes in the
last year which is mainly due to my efforts im making Nixie tubes. Right
now I have to move because I recently switched universities and that is
eating up quite some time too. But I can promise that I have a full box
of Nixie tubes (that is, at least 20 or more), very interesting types.
Japanese tubes, one Indian tube (!), as well as the "N, S, E, W" compass
Inditron by National Union, as well as several other beauties! So: stay
tuned ;-)

Hello, i have been wondering if you own any other interesting/unusual
tubes that arent listed on your site?

Hello,
sorry for reviving this old topic, I found it by accident when
looking for informations about one nixie.
I think it might help you, in attachment is photo of lab sample
nixie from Ericsson.
Unfortunately, I don't have any more information about it, it is
old photo which i download from ebay...

Hi folks,
as some of you may know, besides Nixie tube collecting I am also
interested in the history. I am writing an article, and every
now and
then I stumble upon something that makes me believe that I
will most
likely never finish it ;-)
Here is the confirmed US Nixie tube history: National Union
was the
first to sell a readout tube product line (1954), although
Northrop
aircraft filed promising patents as early as Nov 1950;
however, these
tubes were never manufactured by Northrop (not a single one
of these
tubes has been found as of today). National Union was closely
followed
by Burroughs in 1955 who then offered their "Nixie" tube. But
National
Union beat Burroughs by the nose.
Anyway, I was doing some casual research for patents filed by
Ericsson,
and found patent "GB739041", file is attached. The funny
thing is, this
baby was filed May 9, 1950, predating the first Northrop patent
(US2618697) by more than half a year. The word "improvements"
in the
patent title suggests that this patent bases on other
concepts already
around at the time, but I cannot find out which patents it
refers to.
Any ideas?
The most interesting thing is that Ericsson was probably the
first
company that commercialised the idea of a Nixie tube (and
thus thought
it worth to be patent-protected, that is the logic here).
I feel that the European history of the Nixie tube needs further
research. Has anyone been able to piece together the European
side of
the story?
To be honest, I don't know if this patent is an entirely new
discovery,
but I could not find it on Randall's page:
