Like California govenors, the B7971 boards are back!
The other day we received a totally surprising call.
The estate owner where we had obtained the previous B7971 tubes had found another box of them stashed away in the attic.
So we are happy to be able to offer these wonderful nixie display tubes once again.

Here is a pair of Burroughs B7971 nixie tubes with the driver board for the tubes.
The tubes can display letters and numbers that are three inches tall.
These display boards were used to display stock market quotes.

The B7971 nixie tubes are rare and becoming very difficult to find.
Finding a pair with the original driver board is extremely rare.
These boards have been in storage for nearly 40 years.
They were recently discovered in an estate sale.

The tubes are used, but they are in good condition and appear to still work fine.
The boards include the sockets and mounts for the tubes and the driver electronics.
The boards are untested (we have no way to test them).
The tubes will be tested prior to shipment to insure that the segments will ionize properly.

The pictures above are a sample representation of the boards.
Some boards differ slightly from the pictures shown.

Also included is a copy of the schematics and tube specifications
that were found with the boards (they appear to be a photocopy of a photocopy
and thus a bit hard to read).
