With the parts order having arrived I was able to hook up the circuit
per my idea. It works exactly as I hoped it would. Thousands
(seemingly) of variations based on the settings of the pots. It
outputs a changing voltage right in the range of the intended VCO I
plan to have downstream. Initial
Generally, the '1' is actually two parallel wires,so it's comparable in
length to the other numerals.
Datasheets for segmented displays clearly show different currents for
various segments, but I have not seen that for full-formed nixies (eg, 10
cathodes for 0-9)

For anode-side, I use a PMOS device (see attached picture). The current is
set to (PRDV-Vgs)/R7. You can get Vgs(on) from the datasheet, usually it's
around 4V for higher-voltage PMOS devices. The PDRV signal generated from a
potentiometer and a small 12V DC-DC converter; adjust it to obtain
I have a spare GPS Repeater Version 1 – does any one need one?

What is your method of current regulation? For example, do you use a PnP
transistor or the lm317 method, or something else? I have room to add
something for my anodes, but I'm unsure if using a transistor would be
accurate.

I have a pile (~1K) 11 digit calculator displays and eventually settled on a
0.5mm thick double sided translator board installed with conductive epoxy. The
connection now becomes a simple DIP header: http://www.ebay.com/itm/140729423185
I remember having a bag of the clips back in the '80s and
