Alan, I have stocked up on the 13 pin sockets for Z 566 / Z 560 / ZM 1040 etc., just have a look at my nixie site Jan ... mit freundlichen Gruessen---best...
Other than limiting current in the tubes, either by muxing or just with limiting resistors, how else can one increase their life? The only way I can think of...

... Steve, I just spent some time last week connecting a Radio Shack PIR sensor to a piece of poetry art that a friend was installing in a display case without...
... Steve, a nice thing to maybe try is automatic dimming of the tubes down to, say, 50% brightness when the ambient light level falls below a certain level. ...
David- That's pretty much what I had in mind, except for using a timer chip instead of a CPU. My detector cost me $20 from Harbor Freight (last month they...

Chris, While I like your press-and-hold blanking switch, I would rather have it done automatically. I'm just too lazy to walk across the room and press a...
