12AX7 ECC83 NOS Electro Harmonix

Out of stock


This unused, old stock Electro Harmonix 12AX7 is a high quality preamp tube also known as ECC83. It provides high gain with ultra low noise and detailed, musical tone that rivals the most desirable US NOS types. Unique spiral filament eliminates that filament-to-cathode induced hum common on AC-powered amps. Ships in generic box. Date codes will vary. Approximately 2008 vintage.

  1. Richard P.

    Great prices, super-fast delivery, and my amp sounds great. What’s not to like?

  2. Steve Badgley

    Swapped out an old non-name stock tube in a Behringer “tube driver” with great results.

    Plugged this into my Carvin X60A Combo amp in the V1 slot and cranked up the preamp values along with the bass and mods and treble and presence and slowly brought the master to middle levels to check for noise and microphonic feedback. Had to try this one as the other 12AX7 I just bought failed to not feedback before reaching 5 on the master. Put the other tube into the V2 spot and used a 12AT7 in the phase inverter and played some riffs and a few lead breaks. Warm sounding with ample gain to crunch power chords and sweet sustaining bends. Happy customer once again. Thank you.

  4. Michael Reid

    Great tube in V1 position great tones and low microphonics.

  5. Dawn

    Put this in v1 on my Palomino v32 replacing a microphonic sovtek . Smoother tone than the
    Sovtek, especially when pushed with boost !
