Hi, As I used to leave in the USSR for a while ;-), there is my knowledge about product quality in the USSR: CCCP on the item only means Made in the USSR, but if it's inside pentagon shape sign called

I plan on (eventually) producing clock kits and assembled clocks. Since these tubes are a lot less expensive than nixies (and are alpha-numeric) I think they'll be popular. http://www.tmk.com (general

I think you mean the "OTK ##" stamp. I've jokingly told other tube collectors that that means "nobody from the factory faced a firing squad this week". Given some of the quality variations I've seen,

What are you planning to do with them? I am working on a 12 IV-17 PCB and somewhat universal VFD driver that will be done soon (hopefully, but I keep wasting time on the internet). I have enough tubes

No, his tube has the OTK stamp. It does not have the CCCP stamp. I have not been able to find a difference in used vs new tubes. The only difference I see in his is that his tubes do not have the CCCP

Russian for Union of Soviet Socialist republics (SSSR) The CCCP stamp seems to indicates some sort of Standards approval, I have seen it on some "Leningrad" Light meters. -- Charles MacDonald

No, I picked up a couple large batches on eBay and some others from a private seller I found. My average price for the thousand or so I got was 57 cents each. I've had a dozen or so IV-9's running

Nothing of significance. The melding of the tube base to the envelope on the CCCP ones is gray, while the others are transparent. But every aspect of the internal construction is the same, except for

Thanks for the input, Michail. I have half of my tubes with CCCP and half without. What is the meaning of CCCP?

Thanks for the input. I've been familiar with magic eyes for a long time. I acquired a capacitor tester with one as a kid,

Did you buy those from Sphere's? Their Russian stuff is overpriced. I made the mistake of buying some IV-22 (for $12/ea!) from Sphere. I thought they were something special until I discovered all the

Yes, getting into these ancient tubes tend to get you off into various tangents. To make you really spend more of your money, I see that you didn't mention magic eyes: http://www.magiceyetubes.com/ If
