With a soft and detailed sound, as well as sufficient headroom, the TT 12AU7/ECC82 enhances the sound characteristics of any amplifier, whether it's for guitar, bass, or high-end. These tubes deliver a dynamic range, captivating listeners and musician with uncompromising clean sounds and rich overdrive.

Features:

• Detailed sound
• Ideal for both low and high gain amplifiers

Tip:
Often, 12AU7 and 12AT7 types are used instead of 12AX7 tubes to either reduce the overall power of the amplifier or to just reduce the overloading of the preamp. In comparison to a 12AX7, the 12AU7 brings about a very large sonic difference, typically much greater than switching from 12AX7 to 5751 or 12AT7.

When using a 12AU7 in a driver stage normally designed for 12AX7, the overall power of the power stage is usually reduced. The extent of this difference depends on the amplifier or circuit. For example, a Marshall amplifier with a 12AX7 in the PI stage set at volume 5 will then reach the same volume level with a 12AU7 at volume 6 (perceived volume, not measured).

Application Notes

• Heater Operation: The tube can be operated at 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 operation.
• Coupling Capacitors: Capacitors with low capacitance (typically 0.1µF) are recommended to minimize high-frequency interference.
