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.
Our Range Includes:
We carry the most trusted brands in the industry, available for immediate dispatch:
Tung-Sol: Famous for warm, big tone and low microphonics.
Genalex Gold Lion: The "Gold Standard" for audiophile clarity.
Mullard (Reissue & NOS): Classic British warmth and smooth breakup.
JJ Electronics: Robust, reliable, and great value for working musicians.
Electro-Harmonix & Sovtek: High gain and tight structure.
Variants & Substitutes
Looking for a specific flavor or lower noise floor? We stock these popular equivalents:
7025 / ECC83: Low-noise versions preferred for vintage Fender amps.
5751: Lower gain (70%) for more headroom and a cleaner creamy tone.
ECC803S / E83CC: Long-plate versions for rich, detailed sound.
CV4004 / 12AX7WA: Rugged military-grade specifications.
