Many years ago I bought some NOS B7971s - they came in expanded polystyrene
trays moulded to half a tube lying down, 16 at a time, at about USD 10
each. Whilst they could have been pulls, there was very little ghosting so
I suspect they were genuinely NOS or at least very close to being NOS.
In 1979, Meshna was selling used pulls, without sockets, for $4 (inflation in
the 1970’s was horrible then too). For $5, you could buy what they described as
new unused tubes. I opted to spend $6 more for the six new ones. They are also
branded Ultronics and still nicely individually wrapped in
Based on an ad in the May 1`973 Radio-Electronics, Meshna was selling them
for $2.50 for a pair of tubes with sockets and driver board with HV
transistors, or $1.25 per tube/socket/ckt board combo. These were clearly
pulls from the recently decommissioned NYSE stock tickers, so they probably
B7971 - I’ve only seen the early “Pin type” ones and the later “circuit board” type, what is the other one?RobOn 3 Sep 2023, at 12:44, Robert G. Schaffrath wrote:The only reasons that I can think of are 1) the B-8971 is tinier and might have been more complicated to manufacture. 2) Ultronics
The only reasons that I can think of are 1) the B-8971 is tinier and might
have been more complicated to manufacture. 2) Ultronics having ordered
thousands of the B-7971's resulted in efficiency improvements in
manufacturing the B-7971 such that the price came down.
Off the top of my head I am
Woah what a weird device, very cool find.

And of course the infamous MOD-SIX Black Emerald.

Interesting that the B 8971 is much more expensive than the B7971, was this used in any commercial products ?ThanksRobOn 2 Sep 2023, at 14:13, Robert G. Schaffrath wrote:The B-7971 is an interesting study. It is listed at $15.85 in single quantities, which is still worse than the $5/each I paid
The B-7971 is an interesting study. It is listed at $15.85 in single
quantities, which is still worse than the $5/each I paid for NOS surplus
from Meshna in 1979. However, running that number through the inflation
calculator for January 1970 to July 2023 and I get $128.18 (which is
shocking to
My understanding is that the prices dropped a lot as time went on, here's
another price catalog from 1970 that mentions most of the same tubes for
much cheaper, with B-5750 types just $4@1000pcs - roughly $25/pc now.

Hi all,
Out of curiosity, I took a look at some old Burroughs nixie tube price
lists, and took the prices (1-99 pcs) to an inflation calculator
(1963->2023). Here are some highlights:
B-4991 (Miniature, $68.00) -> $677.10
B-7094 (Jumbo, $45.00) -> $448.08
B-4032 (Miniature, $33.00) -> $328.59
