I have some Telefunken smooth plate 12AX7's (matched pair with balanced sections) that I intend to try, but I a extremely pleased with the stock tubes. I should have mentioned - even with the "noisy" tubes, the noise was never audible at all at normal to loud listening levels - only when I would turn the volume on my Cary up to 10:00+, which would be crazy-loud levels. However, I could have the AE at that level without noise. But with the second set of tubes, I can get to 12-1:00, which was about the same as the AE (and would be speaker-blowing). My Sunfire amp is very high gain, and I use the balanced output on my Cary, so I never, ever get to 9:00 on the Cary's volume control, even in full-tilt boogie. But I think a phono amp should be quiet well beyond what are reasonable listening levels. Again, though, the Transcription is that quiet, with the right tubes.
