[neonixie-l] Re: Any one have a dutchtronix kit or PCB?
My experience with Russian tubes, the 3LO1 in particular, is that they barely last 500 hours. I did an extremely simple scope clock six or seven years ago and I was going to publish it for anyone to make, but I make the mistake of mentioning it on this forum and within days the Russian seller tripled the price of the tubes. I was so annoyed that I sat on it, and then I noticed after three weeks the brightness was fading and in five weeks it was so dim that you couldn't see it in daylight. I switched out the tube and the second one faded in less than 4 weeks. Such a pity, it was a real cutie. So your point 6 is important - secure lots of spares. https://lh3.googleusercontent.com/-peO8sP_m8CI/VW1otYjt2rI/AVk/Q6UxQNz95Rc/s1600/scope%2Bclock.jpg -- You received this message because you are subscribed to the Google Groups neonixie-l group.

I made a bunch of scope clocks in the early 2000s, using the Chinese National Electronics 3RP1As (sold by Richardson). They are most all still running. I personally had mine wear out after about 13 years. That's 100,000 hours! On 6/1/15 3:18 AM, Oscilloclock wrote: CRTs are just fabulous! Welcome to the looney bin.

I switched out the tube and the second one faded in less than 4 weeks. I'm trying to figure out what the wearout mechanism is. Could be phosphor dissociation, color center darkening, or cathode poisoning. What anode voltage did you use? Do you still have the failed ones? If so, care to put one in an oven at 400°F for an hour and see if it recovers? Once I get my variable regulated CRT power supply built, I may do some experiments myself, but I'm looking for early data. To answer Christian's question as to what is a good, long life CRT, the 3RP1/3RP1A is a good choice, as well as the aforementioned Tektronix scope CRTs (except the fancy expansion mesh ones, which are unlikely to be used for art/clocks in the first place). Other good choices are the 3BP1A, 1E36P20, most of the P31 phosphor tubes, and any tube designed for television use (but those are generally magnetic focus and deflection, which is a whole 'nother ball game). I have a bunch of assorted different Russian electrostatic deflection CRTs, and I will be sad if they're all short-lived beasts. - John -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Re: [neonixie-l] Re: Any one have a dutchtronix kit or PCB?
Hi petehand, Thanks for your detailed reply. I agree, its a real shame the 3LO tubes are rather cute! Do you mind posting your hardware for the clock. Schematics and such? Always hungry for some more ideas or intellect. Have you given thought to baking the tube in the oven to see if that helps things? What CRT is ideal for this task of running continuously or for long periods of time. 2AP1 and DG7 ?

Re: [neonixie-l] Any one have a dutchtronix kit or PCB?
Hi Aaron, Thanks for the reply. Yes the CRT bug bit me. Ill gladly share the links. I will post them and copy paste the relevant blurbs. https://groups.yahoo.com/neo/groups/NEONIXIE-L/conversations/topics/44646 shihslakji I made a scope clock using the Russian 3LO1 tube and found the phosphor lifetime is measured in DAYS. It took considerably less than 100 days (more like six weeks) for the brightness to fade to practically nothing in the frequently-written parts of the screen near the center, leaving just the tips of the hands showing. I replaced the tube and the second one went just as fast. They're garbage. http://svo.2.staticpublic.s3-website-us-east-1.amazonaws.com/zloshnik/index.en.html At first I was going to build a CRT clock. But after learning that 3ЛО1И has a very short resource, some 1000 hours, I changed my mind. Zloshnik does not try to be a clock. And now petehand has kindly chimed in for the 3rd person n to say that the 3LO tube is not up for the task as a long term clock. You are right on the auto off and auto dimming, But it seems that the tube still is sub par compared to the other US tubes? Spares are the only way But at XX$a pop, It might be ideal just ot buy a high quality one from the get go. What tube is relatively cheap these days with a long history of proper functioning 2AP1?

Re: [neonixie-l] Ham radios with Nixies?
When I last powered it up a couple of years ago it worked just fine.. :) A Ham radio friend in Copenhagen (approx. 120km away from me) transmitted 1kW in my direction and I heard him just fine - on a few metres of wire in my living room - so it worked :p The same type of receiver has been use in the Danish Navy in the Cold War era warships.. I happened to locate a picture of a rack full of them from Peder Skram (now a museum ship in Copenhagen) ..but I did not save the picture :p I will post further details when I dig it up - it is hiding behind (and beneath) some other large-ish stuff in my hallway so it might first be during the weekend I am able tounearth it.
