Quick Reference Data

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.
