Hey everyone,
Can someone help me determine what brand is this 12AU7A tube (it's made in USA)?
Thanks a lot!

I'm far from being a tube expert, but it looks like a GE / SENCORE based on what's left of the logo.

But how does it sound?!

If I had to bet, I'd say "tubey."

I suppose that's why we don't bet. It's either a telefunken, or a tube.

Indeed a Sencore, thanks a lot!
