There were a few manufacturers making these kind of modules. I have a few
made by TECTROL (Toronto Canada) model SP108A, DC-DC converter, 6V in, 180V
70mA out. It measures 2” x 2” x 1 ¼”. They are potted, so I can’t see
inside.

They were a great find in the scrap yard of a petroleum service provider.
They had recently upgraded an old gas station who was still running VFD
equipped pumps. I was allowed to salvage all the circuit boards. Great find,
except for the one unit that was claimed by wasps before it was turned over
to me! J I now also have a number of 1” high VFD digits as well as some
smaller 2 digit units (Babcock SP-101 and Babcock SP-352). I also found out
they just destroyed a whole bunch of pumps with numitron displays….. L

They are listed in Burrough's Sept 1st, 1963 R55 price schedule - copy on
Frank's pages at http://frank.pocnet.net/other/Burroughs/ReadoutsPrices.pdf

They are called "TRAMAG DC/DC CONVERTERS" and cost USD 48.50 each - a lot of
money. The price schedule is in itself a useful and interesting document...
Nixies were never cheap...

I have one VC12-170 as well - in fact, I inquired about these here in this
group some weeks ago as well, but I got no responses. I did not even know
that Burroughs made these until then.
