(3) To minimize the electrical paths to the outside world, make the
tubes biquinary:

This way only 8 leads are needed, instead of 11 minimum, for a
standard nixie.
Good thinking! The glass wafers for 9 pin miniature tubes ought to be available
Hi,
(2) Laser cutting thin metals (0.015 to 0.080) will not impart much
heat to the metal, and if its pure nickel, then any worry of the alloy
being screwed up, is not an issue (?).
Why not use wires, like in the old tubes? That worked, too. I.e. GA-1,

Hey All,
I agree- a big pinch seal with 10 wires, and 2 'dead' wires for
supports would be easiest.
Pinch seals of that size are also tricky- the tube must be carefully
pre-shaped for the seal; just heating the open end of a round tube
causes it to slump down the middle as the glass thickens up

Excellent summary from someone who actually knows what they are
talking about -
I concur, a remarkable summary, many thanks for that from me as well.
Does anyone happen to know a book covering these topics? I would love to
learn more about this.

How about a pinch seal with an inline row of wires? I've only ever
made those with two wires, but I don't see why it would be that much
more difficult to put 10+ wires through with an appropriate jig.
Induction heating is easy, I built one of those a while back that I
use for other things. As for

Hi,
Was there ever a 60-80mm end-view Nixie made?
Certainly, the CD46 / LD-669 with 74mm, followed by the Burroughs B-7011

I feel that the nostalgic market driver would favor the vertical
tube shape over end view tubes.
Probably. I
