Sound characteristics

Neutral-warm tonal balance with clean, controlled bass, focused and rich midrange and open, non-aggressive high frequencies. Low background noise and a stable stereo image contribute to good micro-detail and instrument separation, without pronounced graininess or sharpness.

Compatibility and application

Ideal for preamps, driver and phase-inverter stages in tube integrated/power amplifiers, headphone amplifiers and DAC/line output stages using the ECC82/12AU7 base. Application is typical in devices from brands such as PrimaLuna, Line Magnetic, Cayin, Jolida, Rogue Audio and similar, as well as in some guitar/bass amplifiers.

Condition and maintenance

Used, excellent condition; visually clean pipes with undamaged pins. There are no specific maintenance requirements other than standard heating and avoiding mechanical vibrations; in most applications, installation is plug-and-play. Service history is not listed; it is recommended to periodically check the performance in the device and, if necessary, replace in paired channels for symmetry.
