Hi Dalibor,
yes, that is my number 2 item on the wish list, the first one is the
needle valve.
What do you do for annealing? Have you built yourself an annealing oven?

I forgot, I bought small glassblowing torch, oxy-gas, it is huge
difference compared to hardware torch. If You have some spare money,
go for it.. You can set the flame to heat just a small area (5mm
diameter) and so...

Hi,
Do You have any info about your progress on your site?
I am currently training my glasswork "skills", which is really a
lot of work, so this eats up all my spare time at the moment. I
will have more time in the next months, so for me it will take
some more time, sadly. Hence, there is nothing to report for my
website as of now :-(
I have a plan, though, for a simple glow lamp with two cathodes
that I will be able to build with my primitive tools and
especially primitive burners. Let's see :-)

Hi folks,
the only tube with a flashed getter I know of is the XN-1:
http://www.tube-tester.com/sites/nixie/data/XN1/XN1.htm
To be honest: I will not use getters at the moment. There is
so much glasswork to figure out for me, that is the part that
I will focus on in the next months. :-)

Hi Dylan,
flashed getters are not used in nixies (I havent seen it at
least), just some VFD tube use flashed getters. Flashed
getters leave a coating on a glass envelope of the tube - we
don't want that. I think that kind of getter needs only
initial activation by heat which could be done by induction
heating as well as in the case of flashed getters. Look to
IN-14 nixie, there is exactly the same pellet.
The only matter to solve will be attaching the pellet to a
wire, but I think that will be possible to do by spot
welding - inspired by IN-14.
Thanks,
Dalibor

Hey Dalibor and others-
I don't feel that these are the right getters for
nixie tubes.
The literature lists them as thermally active- they
only absorb if you put them somewhere hot.
Many styles of getters are made this way; most tubes
do run quite hot, beacuse of the filaments..
There isn't anywhere in a nixie tube that is
constantly 100C-200C. (That's part of the magic of
nixies, of course)
You really want some flashed barium getters; they
absorb gasses at any temperature.

Hello guys,
I've got an offer on getters, tech info attached..
the price is approx. 5pcs/1 eur. Is anyone
interested in it? I will place an order in several
weeks, I may send some pieces sealed in argon filled
tube..
