Thanks for the additional color on these.  I was debating on picking one up
as a novelty, but may hold off now based on your comments.

Well, if you are a collector you might add one or two to your collection at 
the current price, they don't come up that often, but the internal wiring 
is easily damaged - and I suspect that the seller will soon become aware of 
what I know of these Nixies and he might go down on the price! The few 
different sellers I've bought from have showed me photos of the condition, 
with lit digits and easily seen marks on the nixies, before shipping them 
and they have nevertheless turned up with snapped wires - it was possible 
to identify the tubes from the photos so I know that they worked before 
being shipped.

I agree on the pricing; it's not terrible.  The only bummer is that they're
mercury free.

[Fang Taojun]

Hmm,I think I also saw that post on the forum.The seller sold dozens of SZ-2 on 
these days.I think the seller bought them all?
Meanwhile,I don't think it can be compared to other brands in the same 
class(>30mm).Beautiful digits,BUT Short life,rough shape,rough glass...
They proved they can made it,but...they just prove they did it. :-(

I know these tubes, sold from a Chinese local forum with price around 100RMB, 
preproduction model, the biggest top view nixie tube made in China, very rare.

Re: [neonixie-l] Re: Chinese nixies..

[Dekatron42]

I've bought a few of these and other similar types for just RMB 25 from 
China, the digit height is only 33mm, I had the datasheet translated by a 
friend, it says so at the end of the datasheet and I can confirm it from 
the tubes I have.

They are very fragile inside as the wires connecting the digits easily 
break from shaking during shipping, and while handling, and the wires also 
easily short against each other or the internal structures either killing 
some digits or letting two or more light at the same time - they are 
prototype quality and would need a lot more design to become good enough 
for serial production. It seems like the wires break due to being under 
strain and that the welding has punched through much of the wire making it 
snap easily.

They are really quite poor quality for being "prototypes" even if they are 
rare. So I would definitely wait for the price to come down - I have enough 
for a clock and some spares but the poor quality has had me waiting to find 
more at a reasonable price!

There are others with letters/texts inside, I have an SZ-3 (which has some 
broken wires) which shows the texts: Mn, Mo, P, S, Ni, C, Cr, Cu, Si & O 
(mine only shows Mn, P, S, Ni, Cu, Si & O) . I also have a much rarer 
(mega, ultra, super rare ;) ) prototype of the SZ-2, not marked, but with 
the digits made up from wires instead of from etched metal and no Anode 
shield and a rounder glass envelope, otherwise it is identical to the SZ-2, 
see photo below.

These Nixies fit the Russian RSH-32 socket.

Not a bad markup for the seller then!

These look nice, probably going to buy one. I would say the price is fair, if 
they are so rare. Compared to what people pay for German/USA/Japan Nixies >30mm 
digits80$seems fair for a so rare tube. I wonder if the seller has more 
tube types :)

[neonixie-l] Re: Looking for MG-17G for calculator restoration

[Nick]

Hi - welcome to the group.

Are you sure this isn't a driver fault or an issue with contamination on 
the PCB causing leakage?

I have both NOS and ex-equipment MG-17Gs, but I am 3,500 miles from my 
storeroom! If you can wait until April, I can certainly help with spare 
tubes.

Cheers

Nick
