Socket alternatives for B9012

[Jonathan Peakall]

Hi All,

 

I just got some B9012's from Walter. He says he has never even seen a socket for these, so I tjink the odds of finding any are pretty low. :-(

 

So, over the years I have seen some discussions about various alternatives. I tried to search through the archives but couldn't find anything that I was sure would work with these particular tubes. So, any recommends?

 

Thanks! Can't wait to play with these little buggers.

if you find anything relevant, let me know. Right now, I'm planning on using just pins (maybe mounted on a board, maybe flying lead style, don't know yet) so any improvement you find over that would be appreciated.

What pins exactly are you using? I think that is what it is going to come to.

I'll let you know when I know.

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 the Z504S. I'll see if they mate. Or, someone else can confirm, either way, if they are a match, or not. If they are a match, those sockets are currently available, from China, thru eBay. I'll not post that link until I can confirm that they DO match.

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 pins are .040" and the B9012 datasheet says the pins are .043" diameter. A little off, so if it does work, it'll be a tight fit (depending on the style of the pin).

Here's a photo of an original socket.

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 ZM1050 has a trigger electrode for each numeral. This allows the ZM1050 to be used with low voltage transistors.
