Back about 20 years ago, I got a bunch (about 30) B-7971 tubes from an
ebay seller who shipped them wrapped in newspaper.
Those papers are very old, they have 1968 dates. I paid around $11
per tube, a few as high as $17 per tube.
I built a 16-tube scrolling array that scans through an ascii text file
and moves it from right to left across the array.
Those tubes are lots of fun. But it takes a real commitment. And a
big power supply. Got me an old HP-895A to power up that sucker at 175 VDC.

- $150 each
I'm still kicking myself for not buying a bunch of these from PolyPaks
back in the 1970's

Hi folks, I have a
contact looking to sell 4 B7971 tubes. They are untested, but look to be in
good shape from the attached photos. $150 each per tube (which is significantly
less than what they're selling for on eBay at the moment, believe it or not!).
If anyone is
interested, then please contact Jeff directly at k3dua...@gmail.com
Cheers,
Nick
