I don't want to make this a long story or to get pity; however,
My house caught fire 2 weeks ago. Structure is fine. Cause of fire was
salt water tank (not a nixie clock).
Structure is fine, but smoke damage has destroyed a LOT. Reason for my
post is that I have (or had) over 30 nix
Michail,
Sorry about the fire. If modern electronics can be dipped in something,
then tubes can also be dipped in it, I would expect. As long as it's
safe for glassware. The glass that tubes are made from can handle quick
temperature changes.
You might want them to test it on some Russian tu

Many PC board assemblies are given a final wash in what amounts to an
industrial dish washing machine to remove residuals of solder flux.
The only thing I would do is to remove any Nixie tubes from their
sockets, as you might get corrosion between the Nixie pins and the
socket contacts from re
When PCBs are washed, some components have watertight seals on them, e.g.
piezo sounders & transformers etc. Normally a small piece of mylar/kapton
tape is used to protect any components at risk - this is removed later.
You shouldn't assume a board is safe to wash just because it was done

Nope - I have a huge number of tubes waiting for projects, but the main

One moment. Heat was in the environment while the whole thing was at rest:

Well, the BPC856 datasheet says it's rated for 80V, so if it's running at
350V then it's not suitable for this design.
I'd suggest looking for another PNP that can handle ~400V. Digikey has a
400V device that has an SOT-23 footprint (ZXTP08400BFFTA), so that's worth
looking into.
I doubt there
