Very nice!

Ouch.  Never dull, eh? :)

Those tubes typically have a very slow phosphor in them.

Cool!

I haven't pulled any info off of the tube at all.  The connectors are all
potted and I didn't want to dig into it until I was ready to start working
on it.  It's waaay in the back of the container right now, so it'll be a
while before I get to it.

If I can find a 4" round tube with docs, I'll just gut the chassis and
replace the existing tube & electronics.
