High-Mu Twin Triode
The Electro - Harmonix Gold Pin 12AX7EH provides high gain with
ultra low noise and detailed, musical tone that rivals
the most desirable NOS types. The unique spiral filament
eliminates filament to cathode induced hum common on
amps that use AC on the filaments. This tube is a main
stay in many Guitar and Bass Amplifiers.
The Gold Pins make superior contact.
The Electro - harmonix 12AX7EH / 12AX7 vacuum tube is
also a miniature type used as a phase inverter or
amplifier in AC/DC radio equipment and in many diversified
applications such a multivibrators or oscillators in
industrial control devices. They require a noval
9-contact socket.
