Help with Russian 6C3N-EB

[cygnus x1]

I need help identifying this tube, 6C3N-EB. Looking for (near) equivalent US and it's Data Sheet...my Russian is not good. I purchased these years ago and if I had a data sheet, I lost it.

Apparently it's like a WE417 / EC86 with a different pinout...

Klaus has some curves...
