TT 12AU7 / ECC82

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).

JJ 6V6 Red Labe - PAIR - Double Mica Special Edition

2 tubes, matched as pair

JJ 6V6 Double Mica double-layered mica in the upper part of the tube. This stabilizes the tube system and significantly reduces possible vibrations that can occur due to heavy mechanical stress. This version of the JJ 6V6 was specifically designed for use in combo amplifiers.

The JJ6V6 is a beam power pentode with octal base and a maximum plate dissipation of 14W. It has fat low end and full mid tones with very good tone separation and a smooth, clean high end - in general, a very balanced tone.
Currently, the only new production 6V6 which is approved for up to 500V anode voltage in pentode operation.
