I've seen similar Russian VFD panels on Ebay:

Hi Pete,
I like it. I will give this a try.

Pete, that's a nice application for the cascode circuit... Help me
understand how it eliminates concerns about dead time and ghosting.

One more thing about the cascode. Transistor Q1 is dissipating 170mW with
the values shown. It may get a little warm - you have to watch that. You
can put a helper resistor between Q1 collector and Q2 base. The value is
completely immaterial since the current is set by the R2 emitter resistor,

I did mean to change R22 to 10k, but I can suggest an even better way. This
is a circuit I've used to multiplex IN17s, with no dead period and no
ghosting. It looks terrifyingly unsafe. Let me
I will be placing an order for NE-2G bulbs in a few days, and wanted to
know if anyone here is interested in obtaining some. They are 8mm diameter
x 18mm long. The minimum purchase is 1000 bulbs, and I only need about 400.
My cost is about $190 US for 1000 bulbs. ($150 for bulbs, $40 shipping
Wow, sadly I bought as many as I will need for a while. I would've liked
your length more. Mine are about half that size.
