Marconi 12AX7 square getter black plate.
The worse sounding 12AX7 black plate I ever listing to.
kc
this 12ax7 is made by RCA not by marconi.acturely italy marconi original made 12ax7 sounds incredibly good.I think it's one of the best ecc83 I ever heard .
To me ,it sounds lifeless and very weak dynamic ?
kc
I mean original italy marconi made 12ax7,not that one of your picture.that one was not made by marconi. it's made by RCA a US tube.
Have you got some?
kc
this is original iltaly marconi made 12ax7 around 1955,1956.
One of my friend borrowed a pair from me and use them on his NAGRA PLP pre amp,then he refused to reture them to me,He said if i took them back he will sad to die,haha. he think it's the best one he ever heard, not one of.
