[neonixie-l] Re: Sale IN-18

[Jonathan F.]

I believe its like with a lot of russian/soviet products, they were 
produced in factories all day, just to keep all people the job (planed 
economy). Like  IN-12, there are so many those available, they are sold in 
quantities of 100 for about 100$ on ebay. 

And i believe many of the Auctions that include 10+ IN18 Pieces are sold to 
sell them later again, instead of use. 

I've seen a pic on ebay last week, dated 2005, selling IN-18. I bet that 
guy bought them for like 10-20$ per piece and now sell them for the double.

Unlikely. The 4 points that connect each row to the shorting bar have a 
larger area than the external pin that is actually intended to select 
the row. Plus, if you managed to blow them all, you'd have a large metal 
bar loose inside the envelope. Take a look at the pictures here:

[Dekatron42]

Three thoughts:

1. Is it possible to blow these small connections in after production with 
a high current pulse?

2. Many Russian displays where used as backgrounds for a text stencil, 
could this be the case for these?

3. Were they meant to be used in a larger composite display side by side 
and therefore made as one single dot?

Seems very strange to me. I think it's much more likely the metal bar is a 
mistakenly left over detail as the result of a produktion error. It holds 
the pixels in a perfekt row during assembly and when they has been locked 
in positon it's intended to be broken off at the very tiny points that 
connects it to the pixels. Then the bad batch has hit the market instead of 
the shredder...

Yup. I remember a picture of him with stacks and stacks of IN-18 cartons.

Trying to comprehend how the Soviet production system worked is probably 
impossible for westerners. I can certainly imagine that it was simply a 
case of nobody telling the factory to stop producing them, and thousands 
and thousands piling up and overflowing wherever the factory could find a 
place to store them.

There are some displays that seem to be actually rare - I went looking for 
IV-26 Type 2 and couldn't find any (other than single-digit quantities) and 
neither could the sellers I contacted. By comparison, I had quotes for Type 
1 from multiple sellers listing quantity prices at the 1,000 and 5,000 
levels. And the IV-26 is an odd display - they were made by Orzep for the 
sole purpose of being put into clocks made by Reflektor, despite the latter 
being a major producer of display tubes.

There are some oddities like the UDT-3. Every one I've seen has been an 
intentional dud with an internal shorting bar.

And then there are the really rare parts, like this:

I'd say so, Terry.  I know Jeff Thomas (RIP) had purchased upwards of 8,000 
if not more of them when he was selling his IN-18 based NixiChron back in 
the 2005 time frame.  Subsequently, many more IN-18 based clocks have been 
sold since and continue to sell.

What puzzles me is; if they're not being manufactured anymore, how many 
were truly in surplus?   Had to be tens of thousands as the supply never 
seems to dry up.  

I'm sure we'll never know, but just speculating.

There seems to be a never ending supply of these tubes.  Is it possible, 
there were tens of thousands of these in surplus?  

Make me wonder if they're still being produced somewhere in the old Soviet 
Union.

Make sure you research the date-codes; I've seen others in this group 
mention IN-18 tubes from late 1970's and early 1980's are not as reliable.

Unlikely. There was an eBay listing some years ago for some of the tooling 
and parts for IN-18s.

However, at least at the time there was a huge quantity of them with a lot 
of them apparently stored in a flooded basement as the cardboard boxes were 
rather damaged. As the price went up, demand apparently went down, so I 
suspect some sellers are sitting on massive inventory.
