When Only the Best Will Do

The Ray Tubes RESERVE 6SN7 isn’t for everyone. It’s the distillation of decades of experience. With a bespoke design, small-batch production, and meticulous selection, the Ray Tubes RESERVE Collection reveals audio details you never knew were there.

Hand selected and tested, the Ray Tubes RESERVE 6SN7 is designed specifically for hi-fi audio applications. Featuring gold-plated pins and our monocrystalline carbon Magic Coating, the RESERVE Collection easily outperforms New Old Stock and new production alike. Fewer than 5% of production meets our standards.

The 6SN7 vacuum tube is a dual triode usually found in the driver stage of power amps. It’s been used in audio amps since its introduction in 1939. From 1949, it was used in the famous Williamson circuit. Outside of audio applications, it was a crucial component in ENIAC—the world’s first digital computer.
