RAISED CATHODE NEON DISPLAYS 10 SP101 AND 2 SP352
FOR YOUR CONSIDERATION IS THIS LARGE DISPLAY BOARD WITH 10 BECKMAN SP101 DISPLAYS AND 2 SP352 DISPLAYS. BOARD APPEARS TO BE UNUSED, DISPLAYS SHOW NO SIGNS OF BURN OR ANY OBVIOUS USE. THE BECKMAN DISPLAYS ARE MY FAVORITE TYPE OF RAISED CATHODE DISPLAY, AND MAKE VERY NICE CLOCKS. THANKS FOR LOOKING. THE CLOCKS IN THE PHOTOS ARE FOR DISPLAY PURPOSES AND ARE NOT FOR SALE.
This is a NIXIE tube display from an old
HP counter. It uses vacuum tubes for the counting logic.
There are 3 type 47 lamps that shine from back to front through some kind of light tube.
These tubes create decimal points. They might be relocated to form a colon.
A orange tinted bezel is also included.
With a little work and some imagination you
Could build a nixie clock entirely from vacuum tube
It has 7 nixie tubes for the display, and 28 each of
the 5963 dual triode (similar to 12AU7) tubes for the counters.
I took a 5963 from each counter and tested on a tube tester.
They tested from 3200-3400mmho.
The book says that 3200 is average, so the tubes test good.
I have no way to test the nixie tubes.
Bob C. found this great VFD matrix clock on eBay. What is interesting about this is that the matrix is composed of vertical tubes, each containing one column of dots. (Thanks for the link!)
