If anyone wants to build an IN-13 or IN-9 based analyzer, I have all my
schematics etc available on GitHub for this project:

Software (DSP and tube control) is written in Rust. Schematics in KiCad.

I assume the 4.1V DC is filament voltage and the Ua/Ug 24V DC is the anode
and grid voltage now after looking at it for a little longer. I'm not
really a regular VFD guy but I guess I will be more now. I have no idea

Very impressive Paul. I especially like the use of analog filters, seems so
much more in place with nixie tubes. A lot of pain to set up and keep
calibrated, but for the sake of art, it was a good desision!

Here they are in a listing: https://www.ebay.com/itm/324665525805
I bought 10 of them. They look pretty neat actually. I'd be interested in
anyone's figured them out yet? It says in the ad:
ILV3-16/14L-R tube. It is tested - glows perfect. One tube or more. Tested
at Uf=4.1V DC, Ua/Ug = 24V
Crikey, that is a bit of work, a very tidy and a neat solution!
I think I would be tempted to do a linearising, buffering and driver stage
for each tube that takes in an analogue input from a DAC which then just
sweeps across with a DG type multiplex switch IC to each tube driver, that
would th
