12AU7/ECC82

The 12AU7 is a low gain dual triode commonly used in audio amplifiers and hi-fi circuits. It has the same pinout as the 12AX7 but a gain of 20 instead of 100, higher transconductance, and it can provide more plate current than a 12AX7. The 12AU7 is often used for buffer circuits, line drivers and tone stack drivers due to its high current output capability and low impedance when used as a cathode follower.

Equivalents to the 12AU7 include ECC82, ECC802, 5814A, 6189, CV4003, CV491, E82CC and E182CC.
