JJ Electronic ECC82 / 12AU7 Preamp Vacuum Tube

The JJ Electronic ECC82 is a medium-gain dual-triode preamplifier vacuum tube equivalent to the North American 12AU7. It can be used in any circuit designed for a 12AU7 or ECC82 tube and is known for a smooth sound with well-defined tone. Its gain is roughly 17 percent that of a 12AX7, making it common in hi-fi audio equipment as well as guitar amplifiers. JJ Electronic manufactures the tube in Slovakia.
