In the specs it states max Volts between any of the internal elements is
1000V, I wonder if the getter helped to achieve that spec, by removing
residual oxygen??? Ira.

Have no answer, except that if they wanted to have a good vacuum why not
to use getter. But why do they needed the vacuum envelope at all? There
is a version of this stabilizer without the envelope. Just four tubes
packed into a single base: http://www.radiomuseum.org/tubes/tube_zz1031.html

OK... so why a getter in this one? All the little NEON tubes are each already
sealed.

The Russian dekatrons: My guess is they were made as spares for the

As I mentioned in an earlier post today getters are flashed inside of
'VACUUM TUBES' to absorb residual 'OXYGEN' after pump down, and possibly
some external R.F. heating of the internal elements to further degas.
OXYGEN is extremely detrimental to 'hot cathodes', and 'hot filaments',
and will
As I understand it, a getter's primary purpose, within a 'VACUUM TUBE'
is to absorb an remaining 'OXYGEN' from within the envelope. Ira.

I bought a few spare A-101's and at least one had a 1992 manufacturing date.
So I'm wondering what could the former Soviet Union have needed with such
old technology in the 1990's ? I would have expected that they would have
replaced all their dekatron equipment by then, so even spare tubes shou
Hi,
I got hold of this nice Russian EG-5 (ЕГ-5) prototype dekatron and after
having peered down the glass envelope and hooked it up as a normal GC10B it
started to run without a hitch, I made a short video:

Dekatrons use a getter that is flashed and they contain similar gas
mixtures compared with Nixies, as I understand it the getter is there to
absorb impurities from the materials used whereas the mercury is there to
extend the life of the Nixie as it reduces the sputtering.

On Tuesday,
I don't think it would be counter-productive, see e.g. the XN-1. Neon
and argon are noble gases and hence they almost don't interact with
getter material, as far as I know.

Why would they have a getter? An Hg pill that needs to be vaporized, sure.
But a getter? They are used to remove any stray gas molecules given off by
the glass or internal structures due to heat & time.
Nixies are gassed tubes by definition - a getter would be
counter-productive - even during b
