Some guy offering Rodan CD47 tubes

[Ian Sparkes]

There's some guy called Andre offering a number of CD47 tubes here:

Still waiting for further information...

[Paul Andrews]

Whoever buys these, I need to see that clock!

[Ian Sparkes]

Here's something to whet your appetite:

[Nicholas Stock]

What????

Good grief.

They're ugly tubes though IMHO.

[ten kowal]

Aren't we living in times, where the size matters the most?

While they definitely are uglier than Z568Ms, I find them still aesthetic. The neon area looks very slim in such a giant tube, but still visible. 

[ten kowal]

I've got an answer from him. When asked for price for 4 tubes, he answered with 10 000 EUR. 

Well, he really does know how rare and valuable they are.

[Luka C]

I pretty much enjoy "collecting" different types of Nixie tubes and sometimes spend like 100$ or 150$ per tube, but paying ~2500 euros for a Nixie tube is just ridiculous in my honest opinion. I mean, if such amount is something you earn easily and you really feel like you "just have to have one or more", then I can kinda understand it, but if you have to to really spare for quite some times to buy these, you should think about how many other things or experiences there are that you could enjoy and enrich your life with...at least here in Europe, you can buy a brand new car or take a really exotic trip somewhere you'd always wanted to go to. I look at this the same way as with people spending tons of money on some rare Elvis's clothes or similar "collectibles" and wonder do they still feel it was worth it after all the years they own those. Besides, I doubt you can be sure these tubes are NOS or that they have been properly stored for all those years, so you could be buying something that might malfunction in a few years due to gas leaking caused by broken air-seals on the pins and similar defects (of course, you could say this for other tubes as well, but for them you're paying like 15 times less money so you can pretty much replace them in the future or stock up on spares).

Just my 2 cents :)

[Nicholas Stock]

I concur Luka. However, there will always be someone who wants to collect rare things at any cost, so best of luck to him/her, I'm sure they'll find a buyer somewhere...personally, I think nixies should be used for what they were intended, not stored away in a drawer etc...but that's just my opinion, nothing more.

With those kinds of prices, it's just a matter of time before Dalibor flexes his tube making skills and makes an extra large Z568 variant......hopefully!!!

Best to all,

Nick

I haven't seen this type before....

[Paul Andrews]

I am curious where he got them and how much he paid. I'm not suggesting that anyone could do an end-run around him, it would just be interesting to know.

I am a proponent of the free market and one should sell something for whatever someone else is willing to pay. That said, I am doubtful he will get over $2000 for these tubes, not with fellows like Dalibor making them in new production.

$50 for an IN18 is one thing but $2000 for one tube is nuts.

[Luka C]

I don't know how you found that item on eBay, but that appears to be the only nixie tube "seller" from my country that I have ever seen. Actually, he lives like 20 minutes by car away...shame he doesn't have any "more interesting" tubes in stock, these +/- (at least that's what they look like) are not really useful for a clock, heh.

I’m aware that I’m infected with the nixie fever since last year, I’m having problems to stop myself from buying tubes… until now… I think I’m healed :-)

[Instrument Resources of America]

Even if Dalibor can and would make IDENTICAL tubes, (and I'm quite sure
that with his skills he could), they would NOT carry the same
historical, or collector value as these originals. Ira.

[kitehman]

you can treat nixie buying fever similar to cathode poisoning, just hook up your power supply to your wallet and crank i up to 10ma@180v 

[Dan Hollis]

I'd love to see dalibor make a rodan-size (or larger!) nixie.

I'd pay for those.

[Greg P]

I'd love to see Dalibor release something that large but pretty.  The CD47 is butt ugly.  It's like it was a 30mm tube stretched out and poorly proportioned.

$2000-2500 per tube is just insanity, doubt the seller will have many takers.  

Let's go Dalibor flood the market with something better and let the market set the price.

[gregebert]

One of the (many) projects in the back of my head is a 'beer bottle nixie tube', basically cutting-off the top of a brown beer bottle and inserting a PC board with orange LED's arranged like nixie numerals. The tinted glass would obscure most of the PC board, and blur the LEDs so it would have a fighting chance to look nixie-ish.

Trust me, I could make a decent enough clock with 6 of these without spending 15,000 euros....

[NeonJohn]

You could use the modern version of the old edge-lit displays. A stack
of plex sheets engraved with the numbers and edge-lit with LEDs. That
would be even more authentic because the numbers would approach and
recede as they change values, just like in a real Nixie.

I pondered that awhile back, but I remember my first-ever digital clock I built used those same displays (along with stepper relays, kachunk..kachunk..), and the stacked sheets would reflect and scatter light from the previous numerals. It got progressively worse at the rearmost numeral. It was obvious why these displays died-out as nixies became plentiful.

Thin, anti-glare glass that is etched might do the trick, but I dont have the tools to do that.

BTW, I literally abandoned that relay clock because the relay contacts were worn and uncleanable. No regrets.

[Instrument Resources of America]

That sounds really very cool. Any size, within reason that anyone would
want, and much less expensive than Rodan CD47's. Engrave your own, if
you're good at that sort of thing, or have it done somewhere. Multi
colored LED's would also be cool. And just to make sure that the clock
contained some 'neon', use neon lamps for the colons. Ira.

[Paul Andrews]

http://www.thingiverse.com/thing:880429

[MichaelS]

Are CD47's long life tubes?  I haven't noticed any mercury capsules in them.  I've seen some heavily silvered tubes that were smaller versions.  It would make sense if they were made in the early to mid 60's.

It seems that prices of bigger tubes aren't exactly skyrocketing now that Dalibor's tubes are available.

IN18's went up recently, but seem to be coming back down a bit...

[Luka C]

I took a look as well, there doesn't seem to  be the mercury capsule inside, at least from the angles on the pictures available (http://www.leapsecond.com/pages/CD47/cd47-2h.jpg)

Also, you can search for an auction on eBay where the seller sold one defective CD47, this is what he said:

"I have had mine for about 8 years now; carefully stored in a display cabinet in a temperature and humidity controlled lab (No kidding!). Every year, I take it out and connect it to demonstrate this beauty in operation.  This year, she did not light, she did nothing at all!!  In a panic,  I grabbed my sparker, surely I'm just connecting it up wrong?  I sparked her, but she was gone;  her neon gas has completely leaked out!"

So the state and quality of the tubes being sold is kinda questionable considering the price.

[gregebert]

I cant help wondering if the sheer size of that tube makes it more difficult to manufacture with a high-quality seal. They weren't produced anywhere near the volume of other nixies, such as the 5092, so I doubt there was the same level of know-how at Okaya that there was at, say, Burroughs.

Not sure if the surface area/thickness of the glass itself significantly contributes to leakage, or not.

[Alic]

This one went for Eur 700.-
http://m.ebay.ch/itm/262620779109?sojTags=bu=bu&euid=e04cbcdf17644816a4bc528f9f860e65&_mwBanner=1

I still hate myself for missing the end of the auction!

[SWISSNIXIE - Jonathan F.]

I was bidding on that one, but stopped at 600.- € :) . Personally its way to much to pay for an item that "just stays in my collection"

[Roddy Scott]

Isn't inflation wonderful?

And he wants US $2,000.00 per tube?

Rodan CD47 Nixie Tube. (2013 Ebay)

Price: US $155.00

Rodan CD47 Nixie Tube.(2011 Ebay) Price: US $1,300.00

[MichaelS]

Meh.  One sold mid-2015 for $1300 from a reputable seller.

That seems to be a bit much to pay for a museum piece.  Would anyone really want to build a clock with 4-6 of them and actually run them a few hours a day, if tubes were readily available at that price?

[steve....@gmail.com]

FYI, The seller just sent me a quote: 7,000 Euros ($7,393.05 USD) for 6 tubes, which equals 1,166.66 Euros ($1,232.16 USD) each using Friday's currency exchange rate.

[ten kowal]

haha, it seems he realised how ridiculous his price is. 4 days ago he wanted 10000 for 4, which was twice more per tube :)

[Dekatron42]

Maybe he is reading this thread and also getting comments from buyers to read it to get the price right?

/Martin

[Dalibor]

I cant wait to get to realization of similar beast to CD47. Rough shapes - similar height as CD47, a bit bigger diameter (right shape of digits), metal base, long life span, price estimated around $300. The goal is to make large tube, as affordable as possible, for regular use.
Our tubes will not have the historical value (immediately), but will be available, affordable (compared to original cd47) and will come with warranty.

Music to our collective ears Dalibor!!!

I certainly believe that you will be able to do this Dalibor. I foresee
that you will sell many of them, as I think the market is there. Good
luck. Ira.

[Ian Sparkes]

Yaay Dalibor!

Funny you should say that, I was in negotiation with this guy, but stopped. My reason was "Sorry, but I am not interested enough to offer more, especially when Dalibor Farny is offering new, beautiful, guaranteed tubes for much less." I was talking about your current tubes, but this news is even better.

[Dan Hollis]

Wow! I can't wait to see these!

I don't care at all about historical value. I just want big nice looking tubes! :)

-Dan

[MichaelS]

Yay from me too!  Nicely proportioned digits in a well-crafted tube.  I can certainly see using them in something.

I would love to have a CD47 for my collection, but just can't justify paying too much for one when we have better, more affordable options.

[Roddy Scott]

Way to go, Dalibor!

[Paul Parry]

That sounds ideal Dalibor! best get my thinking cap on.. Great news :)

Any news on your CD47 clones? :)

[jb-electronics]

Hi Jiri,

Thanks for your message, this sounds interesting. Having followed Dalibor Farny's progress over the last seven years (and having dabbled in making my own very primitive Nixie tubes [1]) I can imagine how difficult it is to set up a reasonable Nixie tube production from scratch. Do you have any pictures? Any more details? I am curious :)

Best wishes
Jens

Hello, I'm from the Czech Republic and I started to produce digits. During 2019, the Roden size CD47, the production capacity is about 30. They will be available for sale at the beginning of 2020.

Hello,

photos of the finished product will be finished by the end of April 2019. I'm waiting for certification for the European market in the EZÚ ČR Testing Laboratory, in the Czech Republic's law, it is not possible before the certification is ready and the product is in order to publish the photographs properly. he would be penalized without certification. The lab has a lot of work to do and it was done by the end of 2018, and it came to me that it would not be until the spring of 2019. Preliminarily it seems to be all right, but maybe it will have to reduce the amount of mercury, I have about 5mg + Ti, it is amalgam mercury with Titan, it's mercury getr own production according to old patents expired. The amalgam is pressed in a bowl. I do not use the getters of Saes Getters. I will randomly test the whole production series 2019 for lifetime with increased current.

Please keep the photos coming soon. I apologize for the machine translation, maybe it does not make sense. I planned the nixie production in 2003, but it was never time. I have finished my business and started working, and now I have enough time, since 2016 I have been doing this very much.

Don't want to be rude, but this just screams of a scam. If you managed to produce a tube as valuable as CD-47 (which go for $2000, even untested!), why would you charge even less than Dalibor does for Z568M? Providing a photo of your lab and prototypes would be a good start if you want to introduce yourself properly here.

I have production costs (energy and material) of less than 30, -USD per Rodan CD47, and the rest is a profit for work. Dalibor has more expensive digits because he has higher production costs (employee, shop hire, etc.), and because he has no reason to cheat, even if he could have made no trouble and he would have done it. I do not have employees and do not pay the workshop rent and I have roughly a third overhead. Whoever does not understand this must be blind.
