In Reply to: Looking for 12AU7 with "classic" tube sound, a.k.a. Mullard sound. posted by Opus 33 1/3 on February 6, 2016 at 08:50:53:
Talk to Jim McShane about the latest New Sensor offering(s).
JMO, the makers of commercial tubed electronics need to stop "counting beans" and provide sufficient filament current to support 6FQ7s and/or 12BH7s, both of which are in production and beat the living guano out of any 12AU7/ECC82 ever made.
The 12AU7 contains triodes with serious linearity issues. The only HIFI jobs the type is at all suited to is cathode follower and "concertina" phase splitter. In those cases, degeneration (AKA local current NFB) circumvents the linearity problem.

- These are not high-gain tubes, nor is the 12AU7, so what do you mean? - Timbo in Oz 12:59:22 02/06/16 (0)
