OAKLAND, CA, UNITED STATES, July 22, 2025 /EINPresswire.com/ -- Ray Tubes is pleased to announce that RESERVE 6SN7 and SELECT 6SN7 vacuum tubes are now available from its global network of retail partners. RESERVE 6SN7 vacuum tubes are also available as an upgrade option when purchasing compatible Spatial Audio Lab and Linear Tube Audio amplifiers.— Nelson Wu, CEO
Because of their high power dissipation, low distortion, and overall reliability, 6SN7 vacuum tubes are among the most common preamp tubes. They have been used in audio circuits since the 1930s, including in the famous Williamson circuit, and were also a component of ENIAC, the world’s first digital computer. Nowadays, they are widely used in tube amplifiers from companies like Schiit Audio.
“To audiophiles, the 6SN7 is one of the most immediately recognizable vacuum tube designations,” said Ray Tubes CEO Nelson Wu. “Bringing our take on the 6SN7 to market as soon as possible was an easy choice.”
Ray Tubes 6SN7 vacuum tubes are available in both the Ray Tubes SELECT and RESERVE Collections.
