Premium 12AX7 / ECC83 Vacuum Tubes

Whether you are re-tubing a vintage Marshall, a Fender Deluxe, or a high-end Audiophile preamp, the 12AX7 (European designation ECC83) is the industry standard for high-gain, low-noise performance.

At The Valve Store Melbourne, we specialize in providing tested, matched, and reliable valves for musicians and audio enthusiasts.

Why the 12AX7?

Known for having a high amplification factor (Gain of 100), the 12AX7 is typically found in the "V1" position—the first stage of amplification. This means it has the biggest impact on your overall tone and noise floor. Changing your 12AX7 is the easiest way to upgrade your sound.
