Sorry. We are sold out of the B7971 tubes.

We still have some driver boards without the tubes left.



Condition: used

Driver Board Only - no tubes (#B7971-BOARD)
[B7971-BOARD] $15.00

We have a few raw boards available without tubes. These display boards were used to display stock market quotes.
These boards have been in storage for nearly 50 years.
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).
These are the boards as shown above, but without the nixie tubes. The pictures above are a sample representation of the boards.
Some boards differ slightly from the pictures shown.
The boards are being offered at $15.00 each.


Below are links to a copies 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).
