The ECC82-TK Black Diamond Series Amplifier Tube from Telefunken has a dual triode design and is optimized for applications that require medium gain and low-noise characteristics, such as low-noise line amplifiers, drivers, and phase inverters in push-pull amplifier circuits common to Hi-Fi audio equipment. It is also known as the 12AU7 tube, and can replace 12AX7 tubes in lower-gain applications.
