RE: For everyone's info the 12FQ7 is a 12.6v 6CG/FQ7, a far better sounding valve.

Mike, I think Jim is saying that the 12FQ7 sounds better than the 12AU7 and can be used without mods where the 12AU7 is being heated with 12.6V, of course assuming the filament supply can provide the extra current the FQ draws. There should be little sonic difference between the 12FQ7 and 6CG7/6FQ7. True, Jim?
