New JJ Tesla tubes


Greetings, I'm seeking information regarding the sonic performance of the "New" JJ Tesla, Black Sable 12AX7 tubes, especially if you are using them in a McIntosh C2200 or C2300 preamp.

Any info on these tubes is greatly appreciated.

Cheers,

I agree with the few who have said that the JJ 12ax7 don't sound very good. I much more enjoy both the early Siemens 12ax7(Ecc83) with the dual support on the getter and the infamous Mullard late 50's with the "D" getter. However, the new JJ EL84 power tube is very good in the right amp. There is more input on the tube asylum from other users of the JJ 12ax7:

Agree with Undertow on the new manufacture TungSol 12AX7s. Great tubes. Also their EL34s are what I am running in my Marshall Plexi 100W head and these provide that classic sound.
