Ray Tubes 6SN7 Reserve vacuum tube

The 6SN7 vacuum tube is a dual triode usually found in the driver stage of power amps. Itʼs been used in audio 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 worldʼs first digital computer.
