Hi ,

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

There are not many to choose from.

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


Bad option... I had them in my preamp, they didn't last long.


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 .


Ok, but in a preamp they can sound great... and not everyone uses 300B's. I
think they're a better choice than a 12AX7 in many applications where 12AX7s are
used.


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.
