Thanks! I did eventually also stumble on those two but I wanted to be sure
since I couldn't find their datasheets. I did snatch a few 513As so
hopefully it will work out.

Hello,
I'm trying to spell out a word with non-segmented nixie tubes, and it seems
the Dolam LL-555 to 558 series are my best bet for something available on
ebay.
However I notice that the tubes do not include I and O, which I assume
would be done by a numerical 0-9 tube.
I need a suggestion
Thanks! That's alot of positive information - it seems that numitrons are
indeed sturdy devices and they do not need that much protection as I
thought.
What is the frequency of the dimming PWM? I wonder how high it has to
achieve steady temperature due to thermal inertia of filaments.
PWM
Just one correction: inrush current of a filament lamp (or heater) is a
physical characteristic of the component and not something one designs to
happen. Every filament or heater be it huge or tiny has an inrush current,
and the amount of it and the time that takes between this maximum current
I've built quite a few Numitron-based clocks, as well as other displays
using the technology. Personally, I love them: they're easy to drive, last
a *long* time, and are, to my eyes anyway, very attractive. They provide a
wonderful glow, and because they're broad-spectrum, they can be
