It's a lot less work than making IN-18s from scratch, that's for sure.

I am not sure if it is simple to do, especially if you are aiming to 
refill the tube by attaching a stem close to the base. Heating up soda 
lime glass is not a piece of cake, and it is very likely to crack if you 
are not very careful. The proximity to the metal pins at the base makes 
this even more complicated. Hats off to those who can do it! Jens

Re: [neonixie-l] Refilling tubes/different gasses

[Nick]

I'm kind of with Jens on this.

None of the production process is shown and as we know from dalibor, it's 
complex and takes years to get right. Pretty sure dalibor has used different 
gases too.

The Penning Mixture of Ne+Ar is completely standard - the others are 
interesting but maybe not practical due to the high strike voltages needed.

I've made letter tubes using He and Xe- not sure  those would be usable in a 
small indicator tube.

I worked with Richard Wheaton, one of the top hot glass artists in Europe (he 
made the "people like neon' display in our banner), on refilling some damaged 
tubes I had. Ultimately it wasn't successful as the glass in the tubes becomes 
brittle with age and it's very very tricky (read as "not economic") to get 
right for a host of reasons.

Terry,

Sorry for my late reply, its been a crazy week.  I'll box them up and try
to ship them out Monday.

I need more detailed photos, especially of the tube-base connection that 
is covered by the cables in the first picture. Otherwise it could just 
be photoshopped ;-)

Re: [neonixie-l] IN-8 lab model

[GastonP]

IN-8's have the normal 5 and not the upside down 2. This ones seem to also 
have the normal 5, but the red coating makes difficult to see clearly.
I have several (production run) of them, with the thick beehive grid from 
different recent (80's) datecodes and they were all made by Melz too.

[neonixie-l] Re: [OT] AC frequency deviation in Europe

[sonixie]

Same situation here in Italy. I have three nixie clocks around home, we 
realized that they were all delayed in late february. I told my wife that 
there is a tight control of the grid frequency and if they realize that 
they have given away too many pulses, they take them back. She could not 
believe me. Actually, she was right. We had never experienced delays like 
this. though. We were late at work because of this. Certainly 113 GWh 
sounds like a lot of missing energy. Makes you wonder whether this is a new 
kind of crime, stealing electric energy from power lines,  besides stealing 
oil from pipelines or copper from gutters, church roofs and electric
