In Reply to: RE: 6CG7 instead of 12AU7? posted by Ralph on October 7, 2015 at 10:18:39:
My old stock AWV and AWA examples have the same elements as their mfr's same year 6SN7s.The only audio role I would use any 12AU7 (even RCA clear tops) is in follower mode when they are blameless.
That is I would never use any 12AU7 for gain.
It's not really an audio tube anyway, but an RF tube.
The preponderance of 12AU7 rolling posts on the web reflects its non-stellar sound which they all have. ;-)! and ;-).
