Name: 12AU7 Use: Miniature tube type used as phase inverters or push-pull amplifiers in ac/dc radio equipment and as multivibrators or oscillators in industrial control devices. Also used as combined vertical oscillator and vertical- deflection amplifiers, and as horizontal- deflection oscillators in TV receivers. Notes: Requires a miniature 9-contact socket. |
