Hi ,

I don't like the 12AU7/ECC82 at all but .....

There are not many to choose from.

JJ is an (theoretical?) option .....

12AU7 are still reasonably plentiful as NOS items, since they have
become unpopular amoungst hi-end users, imho.

Unpopular as they should be !! It's a dull sounding tube and looks like
sh*t next to a 300B or other power tube .

I think they are marvellous.

I don't ...... IMHO the old long plates are the best , but still a ****ty
tube .
or not ......

P.s.
If it's for a new design the JJ ECC99 might be an option ..... (as driver) .




The 12AU7 is similar to 6CG7 which has 3 dB more gain in most circuits.
The EH6CG7 is, imho, not a nice sounding critter, last time I compared it
to NOS
Telefunken and Mullard, it didn't sound well.
So does the EH12AU7 sound any good or not?

The only way to finjd out is buy a pair, and plug em in.
Its not as if it costs much to do that.
