Ray Tubes - SELECT 6SL7 High-Gain Dual Triode Vacuum Tubes

Ray Tubes - SELECT 6SL7 Octal Dual Triode Vacuum Tubes

The Ray Tubes SELECT 6SL7 is a high-gain dual triode for preamplifiers and tube amplifiers designed to use a 6SL7. It combines two triode sections in one envelope and uses an eight-pin octal base. With an amplification factor of 70, it suits input and preamp stages that call for substantial voltage gain.

Ray Tubes selects and tests these tubes by hand. These have a well-defined bass, a full midrange, and a gently rounded top end. That voicing may appeal to listeners who value the texture of vocals and bowed strings during long listening sessions.

The SELECT 6SL7 is available as a matched pair. A single tube suits equipment with one 6SL7 position, while a matched pair is an option for circuits with corresponding tube positions in the left and right channels. Each package includes a handbook with burn-in guidance and a certificate of authenticity.
