  • Vacuum Tube, ECC803 / 12AX7, JJ Electronics, Longer Plate, Standard Pins, Preamp

    Product Details Vacuum Tube, ECC803 / 12AX7, JJ Electronics, Longer Plate, Standard Pins, PreampT-ECC803-S-JJSold individually The JJ Electronic ECC803 is a high performance, long plate version of the ECC83 / 12AX7. Like all JJ preamp tubes, these are built into a rugged package using the spiral filament and robust plate structure resulting in low microphonics and high reliability. The long plate version of this tube differs from the standard version with its stronger and fuller sound which offers a wider and more balanced frequency response. This tube ranges from deep rich lows to pristine highs covering a spectrum of harmonically dynamic mids along the way. This tube is an excellent choice for any guitar amp and perfect for studio and Hi-Fi equipment as well. This tube will work in any 12AX7 or ECC83 position. Not what you’re looking for?

  • Vacuum Tube, 12AY7, JJ Electronics, Preamp

    Product Details Vacuum Tube, 12AY7, JJ Electronics, PreampT-12AY7-JJSold individually The JJ Electronic 12AY7 is a low microphonic tube built in the same rugged fashion as all JJ preamp tubes. This tube offers the classic warm 12AY7 sound with rich and balanced harmonics when pushed enough to break up. It’s a great choice for authentic tweed tones but can also help clean up amps when used in place of a 12AX7. Additionally, the JJ 12AY7 is a great replacement in 6072 microphones.

  • Vacuum Tube, 5751, JJ Electronics, Preamp

    Product Details Vacuum Tube, 5751, JJ Electronics, PreampT-5751-JJSold individually The JJ Electronic 5751 is a dual triode that can be used in place of most 12AX7 circuits. The rugged build of this tube and reduced gain (30% less than a 12AX7) can improve headroom and give better control in high gain stages allowing users to more easily dial in sweet spots. The JJ 5751 features a smooth and balanced tone and a detailed response with low noise and low microphonics. Not what you’re looking for?
