| Description: | 12AX7 (also known as ECC83)[1] is a miniature dual triode vacuum tube with high voltage gain. It was developed around 1946 by RCA engineers[2] in Camden, New Jersey, under developmental number A-4522. It was released for public sale under the 12AX7 identifier on September 15, 1947. The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications. It is popular with tube amplifier enthusiasts, and its ongoing use in such equipment makes it one of the few small-signal vacuum tubes in continuous production since it was introduced. |
