Hi,
I've decided to post it here instead of eBay, because here I will reach the
passionate collectors (i.e., tube hoarders) of rare nixies. As a tube
hoarder I've collected few odd tubes over the years, but I am no
photographer and never did anything with them apart from testing, so they
are up to trade.
The tubes are mostly Polish early nixies.
Here are the tubes I own and I am willing to sell:
- Dolam LC-2 tubes - those are different from PIE tubes you can find on
Jens or Adams sites, Dolam produced them with hexagonal mesh (PIE has
square mesh):
- Two of them have clear glass, their marking is damaged, but I owned
another one with good markings to confirm they are LC-2s. Also these tubes
can be easily recognized by decimal point being in front of anode mesh -
this is the only tube with such decimal point I know,
- One with red paint - it looks unproffesional and the paint is over
the print, suggesting coating was made post-production,
- One clear glass, but with internal damage - there is gas, but many
digits are not connected due to broken wires.
- Dolam LC-7 tubes:
- Four tubes in very good condition, print is readable, tubes have very
poisoning - nothing severe, just fainter areas on digits, I'd say it's
normal for non-mercury nixies. The leads are long and were never soldered,
suggesting they are NOS.
- Dolam LL-661 tubes - those are symbol tubes matching LC-631s. They
display plus, minus and sine wave symbols. What's odd about them that they
have different pinout than Z567M, while LC-631s are drop in replacements
for Z566Ms:
- One NOS tube,
- One used tube, but working fine.
- Dolam LC-531 with LC-7 digit shape, stack and pinout. Those seem to be a
transition state between LC-7 and LC-531 or just mistake in production.
- There are two tubes, but only one has print on it and the other one
has gas. I count them as inseparable pair with value of one tube.
- Valvo ZM1003 - interesting symbol tube matching ZM1000. It shows minus,
1, sine wave and a spiral (!):
- One NIB tube.
Due to rarity of above tubes* there is no set market value, so I'm
estimating their worth to be 50 EUR each (except the LC-531 tubes, which
would be 50 EUR for both).
*Even here in Poland I haven't traced a single Dolam LC-2 tube for sale (in
fact, I found just one set of photos of one piece of equipment using Dolam
LC-2s) , the LL-661 tubes were the only ones I found on internet at all,
LC-7 tubes were mentioned in just one polish forum and I have never head
about LC-531 with different pinout before getting those two tubes along
some normal LC-531s.
Photos of those tubes are in my google drive, link below:

LC-7 tubes are not photographed here, because I've already posted photos of
it in Neonixie-l group previously:
https://groups.google.com/forum/#!topic/neonixie-l/XHL9G5VNNsk
LC-531s are also photographed in that thread, in last post.
Best regards and sorry for posting a trade offer in the group - I know they
aren't generally well received, but I really think this isn't your everyday
IN-12/14/18 sale.
Tomasz
