Just got 80 new Burroughs PIXIE B-9012 tubes, if any interest

[Walter2]

These are the same glass diameter as the common B-5092/8421 nixies (not as tall), but instead have a circle of 10 digits on the face, 0-9 clockwise, with zero at the top.

Unlike Nixies, more than one digit can be on at the same time (if cathode resistors are used, rather than a common anode resistor).  They need only +150VDC, and very little current.  The digit is small, but the appearance is very interesting, like a Dekatron, but with digits rather than dots. I don't ever recall seeing them used in any commercial gear, but presumably they did appear someplace, maybe another list member has that info.  They can be used as status displays to show up to 10 data items at the same time. They can almost be used as a single tube for hours as well, because two digits can be on at one time (1+0 to show 10, but NOT 1+1 to show 11, 1+2 to show 12, for example), a novel and more "clock-face-like" appearance, but not really ideal.

The base is a non-standard 13 pin (3 center pins, outer circle of 10), so I have no hope for sockets, but clearly loose pins will work fine to a PCB.  Because the numbers appear to race around the outer diameter of the tube when cycled, they would provide very attractive seconds/minutes displays in clocks. Driving is dead simple, ground the cathode to light, just as with regular Nixies, but less current is required (larger resistor).  Because more than one can be on at a time, fading is possible to enhance motion. There are also simliar tubes from Philips in europe, but their drive is quite complex, and they are not interchangeable with these.

Anyway, I will have them posted up to Sphere Research shortly, or you can just email me for more details. I have the factory data sheet as well, and I will email the PDF to anybody interested.  They will be quite cheap, but there's only this one single batch available, no more stock after this, and frankly I was surprised to get these. The appearance of this batch is excellent.

all the best,

I may be interested in a couple, but I'll have to do a little research before I decide to go with these over nixies. I am building a clock out of an elevator panel and I am thinking I should keep it all neon :) I'd need two for minutes display at least.

Hi Walter,

I may be interested in a few of these B-9012s depending on the price ("quite cheap" being relative). How much are they each or by lot? Are these NOS or used?

Could you send me the datasheet?

Thank you,

Jon D.

[M.J.Sangster]

I'm also interested, depending on price.

Thanks,

Michael Sangster

I too would be interested in some.

Thanks.

I’m interested.

Tell me about pricing.

Always interested in new tubes for clocks.

On your web-site ??? I've looked several times and don't find them

He said in the first post to email him' so I did. Turns out these went FAST. I don't think he has any left, but you can check. I hope he walter has no problem with me passing this on.
