In my constant search for vintage stereo equipment I happened across these tubes.

There are 5 tubes, all with sockets. 4 of them are attached to the original aluminium brackets that have been cut in half ( two brackets originally) and one "spare" tube with socket.

They all appear to be in very good condition, glass is very clean with no noticeable scratches.

Also included is an original copy of the Burroughs data sheet for the B 5971, 8971, and 7971 tubes

I have NOT tested these tubes, I have no way to test them.

I am willing to accept reasonable offers, however I will not accept paypal as payment. I have major ethical issues with ebay and paypals business practices.

That said I will accept, google wallet payments, amazon gift cards, cash (if you pick them up), or other options if you have any suggestions.

I will also gladly test them if someone wants to send me a power supply first, I will test each segment individually.

May also be willing to accept a partial trade for a small nixie clock like an in-12 or in-14 based unit or kit.

If you would like any other pics please let me know.

I am in Terre Haute Indiana if you are close and would like to pick them up.

probably a silly question after all this time, but have these been sold?

Thanks.

I would be interested if they are still there...

I have acquired two displays with Burroughs B-5991s in BIPCO BIP8211P sockets. Two tubes in one display seem to have been wrongly replaced by B-59956 tubes, which have offset digits, presumably because they contain left decimal points. I don't think that these decimal points can be driven by the BIPCO sockets.

Can anyone identify where these displays came from? I am inclined to think aviation or other military use, but maybe some other industrial instrument?

Has anyone tried using the BCD to decimal built into these tube sockets? Is there a good way to test the sockets, other than to fire them up and see if they work? I'd quite like to keep these units intact.

Nice find!

Bipco modules were basically convenient packages for driving top-view tubes, - I have several different types of these, some with 5991 nixies, some empty.

Threeneurons has all the data sheets & schematics you'll need at https://threeneurons.wordpress.com/links/data-sheets/

I'm not sure that they were ever for anything specific - just the opposite - they were general purpose modules that made their way into lots of kit.
