That's pretty definitive ! A LM9022 is a LM4871.
Yes, extra brownie points, for opening one up, and the photos ! I didn't
expect to see the actual part number ! An internal code, that translates to
a part number, but not the actual part number.
Mouser has over 4000 of them. Not bad ones-n-two-zees prices. $1.42 on a
reel tape, $1.71 in a rigid tube. And a good price break if you get 10 or
more. Probably same prices at Digi-Key and Newark (Farnell).
They're not the same base as the B5092 ???
If not, then here's what I do:

I have one B9012, that I got years ago. I also have sockets for the B5092,
which are also good for other nixie tubes, and dekatrons like
First off, B9012 is two concentric 'circles' of pins, though one of those
circles is only 3 pins so it's not really a full circle...
But anyway, no, sockets for these are unobtainium because of this two row
thing. I saw that page, and even before I saw it, I was wondering the same
thing. D-sub
You guys are right. I just found my B9012, and its an odd base.
The tube that can use the same socket as B5092 (13-pin) is the ZM1050. That's
Philip's pseudo pixie. I have one of those, too.
The main difference, other than the base, is that the B9012 has a cathode for
each numeral, while the
Thanks!
Now after some more testing I have the RYG10 up and running at 100 kHz (the
limit of the oscillator that I am using right now) but I guess it will run
up to the specified 300 kHz. The driving stage now uses either a ECC960 or
a ECC962 (or their counterparts E90CC/E92CC) as I have a lot
