Just noticed your link changed in your post. It is supposed to be a T at
the end, instead of a slash T.

Major thing I just noticed.....
All my tubes have always had the CCCP logo on the back.

Your tube(s) does not.

Do you notice a difference between the ones with and without the CCCP
stamp?

Thanks for the input, Michail.

I have half of my tubes with CCCP and half without.

What is the meaning of CCCP?

CCCP is Russian for USSR.

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 very slight differences in texture and color of some materials.

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.

No Microsoft Products were used in sending this e-mail.

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 stamp.

Quote from another....
Actually, OTK means Quality Control Departments. Such mark has a personal
number of the worker who tested the tube, and found it is within specs. If
later discovered that the product is out of specs OTK manager knows who is
guilty, by the personal number that belongs to the tester.

It does not mean "Highest Quality". It means, "Tested by Worker Number
###" -- the way to force workers to test actually, being afraid to loose bonus
that is a significant part of a salary.

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, I don't think it means the tubes were each inspected.

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 Sign of quality, then it's almost the best USSR quality product. This sign picture you can see here:

OTK is equals QC (Quality check/control) and virtually all products must have it, but not nessesary it should be seen on the item. It could be in the item passport or User Manual/ datasheet.

Another quality check is the military one. The item, which has passed military check has the highest quality and items/components for military devises could be selected from hundreds or thousands item stock. The problem is that they usually does not have any specific sign, sometimes these items stamped with 2 Russian letters "??"

I hope it helps.
