I'm looking at an RCA clear top right now. It has both tube numbers on it and no shield between triodes.

In my experience, the black plate Tungsol 6CG7 was an excellent tube. The kind with the inter-plate shield.
I hope he does post that. It would make me feel better lolJust promise us one thing. If you buy those $750 tubes, you won’t be posting here how they aren’t any better than a $40 pair you could have gotten on the cheap.

I have a set of 4 black play RCA 6cg7's I have not used them with an amp yet.
