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,

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.
