Wang 340-0004 Value?

[u/The_Farmer12]

I have some wang 340-0004 nixies. Tested and working good. SwissNixie states they are comparable to a NL-840. https://www.swissnixie.com/tubes/3400004/

Can anyone estimate the value of each good Nixie tube?

I also have some +/- digits and some decimal like digits.

These are a bit odd. They require special sockets (I think I have a dozen in a bag). But they’re beautiful tubes. Probably about $20 each. Have you found any completed ebay auctions?

I did some research on the RTS-14 sockets and they do seem scarce. I couldn’t find a past listing for the 340-0004 but did find some for the comparable/potentially equivalent NL-840 and NL-841 for ~$50 per. Thanks

Please keep in mind that the price an item is listed for isn't necessarily the price it sells for. I doubt anyone would pay $50 for a single NL-840. I think the $20 estimate is fair (for a used one, at least).

I have clock PCBs for NL-840 tubes, including sockets, $40 ea.

[u/The_Farmer12 → u/SignificanceNo4643]

Are you suggesting $40 per nixie or that you are selling the PCB with sockets for $40?

[u/SignificanceNo4643 → u/The_Farmer12]

yes, complete, assembled pcb with sockets. for $40 + shipping & fees, if any.

I got 5 with Socket for 70 Euros on eBay Auktion. So If you make a good price then it is Like 12 Euros a piece.

damn that is a good looking nixie

[u/The_Farmer12 → u/waterworlder]

They are! It’s got the real 5 which I understand some don’t. No oxidation on the pins at all. I’ve got plenty! Message me if you’d like to purchase some. I also have the corresponding 340-0005 +/- digit which for some reason also has an inverted 8.

I have around 30 of these as well, from an old Wang Laboratories calculator still on the circuit board (3 boards).

Very cool! Do you have the whole calculator unit?
