Greetings everyone!
I am currently offering to help a friend of mine, who
is new to nixie tubes.
He is a retired telephone company switching tech, and he
has a solid electronics background. He has made a few
scratchbuilt clocks, and has them running using 7-segment
LED readouts.
He also has built an all-relay clock based on the
circuit drawing of the Western Electric #5 crossbar
telephone exchange's "time of day" clock. That is a sight
(and sound) to behold. Its visual output is lamps.
He did find and purchased some 7441 driver ics and I gave
him a few various nixies to test. I also gave him a copy
of the National Readout Tube data brochure.
Lately he has been scouring ebay looking at various tubes.
There are some NL-5440s up for auction with sockets right
now, but with no bids, and we both wondered why.
That reminded me of the infamous Richardson bulk buy of
5 or 6 years ago, when those thousands of NL-5440s and
NL-840s were purchased.
So, I am asking here on this forum, in behalf of my
friend, if anyone out there might be willing to wheel
and deal on some of those Richardson bulk buy tubes.
(Or any other tubes, for that matter...)
Such as 8422. Any of those out there for sale?
He is only looking for maybe ten or a dozen tubes
and with sockets if available.
Just thought I'd ask here to see what might be out there.
Thank you!
Chuck Richards

I think there auction is too expensive.84$ for six tubes.
I have many tube in stock before,but I have sold on ebay last weeks.
But I think someone will sell to your friend.
Good Luck!

I highly recommend Burroughs 5092 tubes because they are very durable and still available fairly often on Ebay (hurry, there's a buy-it-now for 5 of them right now. ).
You can also get new sockets on Ebay for a good price as well (my last purchase of 15 sockets just cleared customs in SFO).
