Anyone have an idea of what the circuit is, or should I setup better pictures.
Twp giesses. given that there are 14 cathode driver transistors and current
limiting resistors. It's a 2x1 multiplex, driving the tubes alternately, or
(more likely), it's using them direct drive, as 7-segment
Yes, I read that. :)
The circuit board is home made. Looks like a couple of traces were
rerouted after it was made.
I will look more into it and post results with my limited knowledge.

Now more curious than ever
going to take to work and take pictures to post.
The problem is that the octal sockets are empty. So, I don't know what
tubes would have been in them. I mis-read the auction as it said they were
included (but what was meant was that the sockets were
Well spotted. A seller (and their sock-puppet) to avoid...

What I found more interesting was the bidding pattern for that unit.
The bidder with a 31 feedback rating, who bid 18 times was also
bidding exclusively on hikerjims
Jeff,
Yup, noticed that as well. Also, I even emailed the ebay seller without
response.
For my purpose, I was not bidding against his shill bidder since he dropped
off early on, so I was OK with the purchase.

Hello,
Only took a few temp photos...

Real fast - without powering up and taking apart wire loom
3 octal sockets.
Pin 1 on each tied together and go to input or output side of 7805 (can't
tell since using same color)
