Description
The Electro-Harmonix Gold 12AX7 is a premium variant of EHX’s well-regarded standard 12AX7, distinguished by a gold-plated grid that reduces electron scatter for improved linearity and lower distortion. The result is a high-gain dual triode with a notably warm, three-dimensional sound that appeals to both audiophiles and demanding guitar players.
The 12AX7 (ECC83) is the standard preamp triode in an enormous range of Hi-Fi and guitar amplifier equipment. With a mu of approximately 100, it is the highest-gain common preamp valve, making it the natural choice for phono stage and first-stage amplification duties where every decibel counts.
Compatible with any 12AX7, ECC83, ECC803, 7025 or 5751 (at lower gain) position. Excellent in phono stages, guitar amp V1, and Hi-Fi preamp input stages. Single valve, tested before dispatch.
