The EF86 is a high gain pentode designed to amplify low-level audio signals. Introduced in the late 1950's, it is used as a preamp in audio equipment and instrument amplifiers.
This pentode is selected for low-noise and low microphonics and is used in many (european) hi-fi preamps. It recently gained popularity because it is used in many new guitar amps based on the vintage AC15 Circuit.
Very quiet and dependable.
