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.

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.
