Tube-Town E83CC Preamp-Tube

High-quality 12AX7 / ECC83 / 7025 preamp tube with low background noise and reduced feedback tendency due to short anode plates, as well as a powerful bass and a dense sound. Very suitable for input stages with high amplification or amplifiers with generally high gain.
Dropin replacement for all 12AX7, ECC83, 7025, and E83CC tubes.

Application Notes

• Heater operation: The tube can be operated with 6.3V or 12.6V, depending on the circuit design.
• Grid resistors: It is recommended to use grid resistors of at least 1MΩ to ensure stable functionality.
• Coupling capacitors: Capacitors with low capacitance (typically 0.1µF) are recommended to minimize high-frequency interference.

TT Selection: V1 - Low Noise
This tube is selected for sensitive input stages (V1)

Sweet and warm sounding preamp tube with high gain. We recommend this tube for guitar/bass amps.
