This sale is for ONE Burroughs B-7971 Nixie Tube. Each tube has had every pin / segment tested with 170VDC and 10K ohm resistor and they are fully functioning beautifully with no dark spots or segment-to-segment shorts.
This sale is for lots of "Pin-Top" version of the B-7971. The rare "Pin-Top" versions are made with a darker background on the segments that provide better contrast. Check out the video HERE: youtu. The PCB's with the frames are pictured.
If you choose to use them, you're on your own to figure it out. IF you attempt to return the tubes under "NOT AS DESCRIBED" or "DAMAGED" AND THE MARKINGS ARE MISSING, ALTERED, OR DO NOT MATCH MY PHOTOS and stock markings/date codes do not match my photos, then. Do not attempt to return to me YOUR malfunctioning or broken tube. I have to make this clear because I've had people attempt this fraud with me in the past. Markings can be removed with a Magic Eraser.I sell high value tubes regularly. It's very rare that anything goes wrong. But when it does, I need to be absolutely clear what the terms and conditions are. I work hard to make sure buyers are happy.
