Aspen Pittman is selling off machine tools, and vacuum tube parts on eBay.
These were from the Owensboro GE plant. They include grid forming machines,

I was wondering if anyone ever attempted to design a nixie clock that
is completely made up with tubes?
I did a rough estimation and I came to about 30 ECC83 tubes to make a
(24) hour and minutes display. That sounds like a realistic number, so
perhaps someone has designed that already.

I've seen several on the net, this is still my favorite:

WOW that is totally cool! It looks even better than what I would have
expected!
He said he's not running the clock all the time because of electricity
bills :-) It looks like it consumes over 0.5kW!!
Fantastic project, thanks for the link!

Are you including power supply and timebase in your calculations ?
Actually, the ECC83 (aka 12AX7) is not the best choice for logic. The
ECC82 (12AU7) or ECC81 (12AT7) would be better

Quite a bit of interesting technology there, especially the clock that
is only made with neon bulbs, who would have thought that? Certainly
not me :-)
I came up with this question as I have an old batch counter that uses
discrete transistors for it's BCD counters and decoders.

In short, yeah, I've bought a tube from them, and received it.
In detail, if you're curious:
Yeah, I requested an AMH-10 and another tube from them back in April. They
were out of the other tube, and quoted me a price for

I was surprised to see so little transistors there.
The BCD boards look to have 8 transistors arranged as four
I am interested in this seller too. There are two Russian sites that look
extremely similar and one of them has a weirdo CRT that I would like. I held
off ordering because they would only accept direct cash via a service I have
not used or know about OR via Western Union. I feel much happier
Ah, that is reassuring; I must check if Anton still has the CRT I want.
Pity that stories of 'baddies' out there make us so wary of everyone !

The BCD boards look to have 8 transistors arranged as four flip-flops. This
makes the decoders easy, as the flipflops have Q and not-Q outputs for each
stage, so a simple wire-and lashup with some diodes will do the trick. Cute
construction with the long narrow board perpendicular to the

That sounds like something crazy that I would dowhen I got a few
free thermometer counters.
