can you I.D these tubes?

Hi,
I bought a Z28 and I love it...

The guy gave me a couple of extra tubes and I can't identify two of them....maybe you can help?

They're an EF86 type
Tube #1) the logo is a circle with a "C" in it.
in the center of the C is 6*32 and then something is rubbed off...
At the bottom of the tube is X 65
All this is written in black.

Tube #2)
Almost all is rubbed off with a bit of a white printed circle and under that is ef86 in white and nothing else...
what do you think?

Hard to say. My guess is that they're Russian EF86s that went microphonic.

Hi,
In searching on the internet I identified one of them; tube #1.

It's a "winged C" brand.

the other one still is a mystery.

Winged C would indicate the only new production EF86 which is branded in a multitude of ways.
