RESERVE 6SN7

The 6SN7 vacuum tube is a dual triode usually found in the driver stage of power amps. It has been used in audio since its introduction in 1939, and by 1949 it had become the driver of choice in American builds of the famous Williamson circuit. Beyond audio, it was a crucial component in the world's first digital computer, ENIAC.

Minimal Microphonics

In certain uncommon conditions, 6SN7 vacuum tubes can experience elevated microphonics. The RESERVE 6SN7 includes a rubber damper, one per tube, that can be fitted to isolate the tube from vibration.

Sound Characteristics 

The RESERVE 6SN7 offers a warm, natural sound with smooth treble and an outstanding midrange, and a relaxed vintage character that suits small-scale jazz, vocals, violins and brass.

  • The bass emphasizes an organic, fluid sound that makes it especially suitable for small-scale jazz and vocal performances.
  • The midrange frequencies are a key strength, with warm and expressive vocals offering a relaxed listening experience.
  • The treble performance emphasizes refinement over analytical detail, making instruments like violins and brass free of harshness.
  • The dynamics are well-balanced, while the soundstage is expansive with excellent depth, stereo separation, and layering of sound.
