Brian. Sent you an email. I have no use for the db9 or bnc so those are good missing parts lol. Please be aware you have an invound email. Thanks for the offer !!

Re: [neonixie-l] Re: Any one have a dutchtronix kit or PCB?
If they fail that quickly and the damage is concentrated in the center then it sounds like it could be also be ion damage to the phosphor as opposed to an issue with the phosphor itself. I'm not sure how good the vacuum is on some soviet tubes in general (I suspect it varied from factory to factory if not day to day) and most electrostatic CRT's of this era don't seem to have an an aluminium layer or an ion trap to protect the phosphor.

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.

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 ?
