I would say that the 6L6 has a contribution to that, but it's very small. The main culprit is the tone stack. Before the 5F1 I had a small Fender Champ 600 RI which is a slightly modified blackface circuit with a very pronounced mid scoop. That's why I sold it and got the 5F1, actually. The 5F1 is a tweed, not a blackface model circuit, and it gives you more mids.

So IMHO the scooped thing is really a function of the blackface Champ circuit, not so much a function of the power tube.

As for the chime, by chime I don't really mean high end in itself. I mean shimmer - well, it's hard to explain sounds in words .
