Giant B-7971 Nixie Tubes Available Here! Reliable and Honest

[USMintQuarters.com]

Greetings,

I am respectfully submitting this information to all Radio and
Electronic enthusiasts, collectors, clock makers, tinkerers and
dealers in this newsgroup. This may be of interest to anyone looking
to obtain Old, B-7971 Burroughs Nixie Tubes.

Available while our supplies last are these Giant, Alphanumeric
Burroughs B-7971 Nixie Tubes. These historical tubes of yesteryear
were developed in 1952 and used throughout the 1970's as displays for
everything from Early Computers, Aerospace, Submarines, and the
display of stock prices on the NEW YORK STOCK EXCHANGE.

We pulled them from an old warehouse, Perfectly Preserved and wrapped
in paper to protect them from the years of age. Many
electronic/electrical tinkerers have been using them for new and
interesting projects such as Nixie Tube Clocks.

We ship overseas and also have available the Original Sockets to
accompany the tubes, which are necessary in many applications and are
as equally Rare and tough to find. Our tubes are in working order and
although we do not test them individually, 99% of the tubes sold to
date have worked perfectly! All of them are still as we found them
wrapped and boxed. NO Complaints with our service or quality to date,
and we hope this will be a good resource for those interested in this
type of old technology.

Any questions, please
Contact the Webmaster at webmaster@usmintquarters.com and we will be
happy to answer them. Thank You.

Interestng. I got some old Nixie tubes once and every single one was
gassy. A couple worked somewhat with the "blue" haze.

There's a trick you can do to reactivate the "getter" involving
heating in an oven... but it only works for mild to moderately
gassy tubes, not dead ones.

There are a couple of other possibilities which seem likely, since when nixies
leak they usually just quit working:
A) The tubes you had were late-production "ultra long life" types with high
mercury content. These usually exhibited the blue haze, even when new, which
is one reason why they were always installed behind an amber filter lens in
the original equipment which used them.

and/or

B) You were severely overdriving them. Even the earlier types with no or low
mercury content typically used a "Penning" mixture of neon and a small amount
(1-2%) of argon. When overdriven, the blue/purple argon glow becomes much
more noticeable. The blue haze of ultra long life types gets much worse when
overdriven too. Nixie tubes are current-operated, and like any gas-discharge
device exhibit a "negative resistance" characteristic which requires external
current limiting (typically a resistor in series with the anode). The most
common sizes of nixie tubes typically operate best in the 1.5 - 3.0 mA range.
