How does a nixie behave in the first few hundred micro seconds after
switching off. Is it resistive, capacitive or inductive? I would
assume it to be capacitive but that is not exactly what I measure. It
seems more resistive, so I am wondering if this is normal or am I
doing something wrong?

Fifty volts is barely enough to work, but it works for at least B5870s.

Nope. But the MOD-6 has a nice SEGTST function.
I use the MOD-6's power supply, a couple of clip leads, and some 22K
resistors. For partially-poisoned segments, I just parallel
Ucc is a common term for supply voltage [Google it]. The 'cc' is probably
questionable in this case, but the U is common in Europe.
Semi-related Factoid:- If you read early US books on wireless you will find the
term "anode" used in a sentence when they mean the supply voltage for the
tubes. Ma
Yes, the clamping voltage is a little too low - I've tried them. They
do work but a bit too much haze from the other cathodes. You might get
away with it using coloured tubes.

Tis strange how the brain works. I sub-consciously knew that 'U' stood
for voltage, but never thought about it. I suppose being from the UK
that I see Volts written as U quite often so never questioned it nor
knew those over the water are not familiar. Did get me thinking
though, where does the 'U'

Hi all-
I had a question on driving nixies using something other than 74141s.
Would any driver that can sink higher currents work ok? Am I right in
assuming I can use a driver that sinks with nixies because the cathodes are
connected to ground when not floating?
For example, would this one w

I noticed it appeared to be missing too, and emailed the seller who
confirmed that the 'pinch' on both tubes was complete and intact.
Still, I did not bid.

Unfortunately, the only way to test a tube like this is to apply high
