I have 3 russians 6sn7GT who have a "CCCP" on the case. Is this a good valve?

Thanks,
Felipe

What manufactures make this valve with this case? A friend called me who is CCCP is Union of Soviet Socialist Republics...

But the question isn't the manufacture, is if this is good or isn't good.

Thanks,

It's probably a Sovtek. I used the Sovtek 6SN7 in a recent project as a cathode follower driver. Works just great: the characteristic seems quite close to the plate characteristics of the RCA 6SN7 (measured gain and Q point were quite close to the design nominal values) the Sovtek includes grid radiators that other brands don't include, the tube isn't at all microphonic in that sharp rapping on the envelope didn't cause any disturbances when o'scoping the output. A lot of US produced 6SN7s seem to be horribly microphonic.

No complaints here.
