The 12AU7 and its variants are a miniature nine-pin B9A base medium-gain dual triode vacuum tube. The tube is popular in hi-fi vacuum tube audio as a low-noise line amplifier, driver especially for tone stacks , and phase-inverter in vacuum tube push—pull amplifier circuits. It was widely used, in special-quality versions such as ECC82 and A, in pre-semiconductor digital computer circuitry. Use of special-quality versions outside of the purpose they were designed for may not be optimal; for example, a version for digital computers may be designed for long life without cathode poisoning when mostly switched to low-current mode in switching applications, but with little attention to parameters of interest only for linear applications such as linearity of transfer characteristic, matching between the two sections, microphony , etc. Double triodes of the 12AU7 family have a center-tapped filament for use in either 6.
