Faulty B-7971s

[Mike Harrison]

My listing - no idea if anyone has a use for bad B-7971's

3 of these have been running 24/7 as a clock for about 15 years, other was faulty when I got it

When I had partially it segments, I was able to fix it by increasing the anode voltage to about 180-190V.  Others have reported fixing shorted segments by hitting the tube, gently; you almost have nothing to lose.

Dang, I don't think I've ever seen 7971 tubes that black. Maybe it was just the lighting.

For stuck segments, I've had great luck dislodging them by smacking them around.
