Thanks John, that is useful information!
Yes, you confirm my fear. Fortunately I bought the tube as am collecting item,

To Eric's question on the N3...
These are also rather tricky tubes. My experience is similar to Martin's -
unfortunately many examples of N3 are non-functional in that they won't
even strike a glow - outgassed or similar. I fear that if you can't raise a
glow with a violet ray unit or plasma
The sticking on K10 specifically is a peculiarity of the 6167 in my
experience. I believe it's distinct from the sleeping sickness effect that
Martin describes as that is essentially random in which cathodes are
affected (and as he says, working the tube, possibly at elevated current,
in both
When I had initial problems with my A101, I increased the steering voltage
by using a larger cathode resistor and it's worked flawlessly ever since. I
couldn't tell from posted scope trace what the measurement was. Also, you
want to have overlapping waveforms, with no dead-time, to ensure the
Hi Martin,
No, I was not aware, despite Giorgio is a friend of me….
Thanks for your tip and experience

Regarding the Pressler N3, I hope you have seen the datasheet here:
http://lampes-et-tubes.info/cd/N3.pdf
Out of the bunch that I own of these only a few are running (and maybe half
are out-gassed and some have mechanical faults like loose welds and pins
rumbling around inside the envelope)
Hi all,
Unfortunately no further info here.
A guess is it a kind of cathode poisoning??
Did you already contact the TCA [ tubecollectorsassociat...@groups.io ]. They
are based in the USA, so the chance is greater there is info to find.
I have the same problem with a rare Pressler
I see this a lot in some Dekatron types/brands that have been stored for a
long time, some brands have fared better while being stored compared to
others and some very´seldom experience this problem. I usually just
increase the current either by raising the Anode voltage or decreasing the
