Ray Tubes - SELECT 6SN7 Octal Dual Triode Vacuum Tubes

Ray Tubes - SELECT 6SN7 Octal Dual Triode Vacuum Tubes
The Ray Tubes SELECT 6SN7 is an octal dual triode commonly used in the driver stage of a tube power amplifier. Its two triode sections share one glass envelope, and its amplification factor of 20 suits circuits designed for the 6SN7. It’s available for replacing a worn tube or comparing a different voicing in equipment that specifies this tube type.
Ray Tubes hand-selects and tests the SELECT 6SN7, with fewer than 5% of production meeting its SELECT standards. Gold-plated pins help resist corrosion at the socket contacts. Ray Tubes describes the sound as full in the bass, warm through the midrange, and clear in the treble, with distinct instrument placement in layered recordings.
The SELECT 6SN7 comes individually or in sets of two or four, so listeners can choose the quantity their amplifier calls for. Each package includes a handbook with burn-in guidance and a certificate of authenticity and warranty.
