Ray Tubes - SELECT 12AX7 Dual Triode Vacuum Tubes
The Ray Tubes SELECT 12AX7 is a high-gain dual triode for compatible tube preamplifiers and amplifiers. Its two triode sections share one glass envelope, and its amplification factor of 100 suits circuits designed for substantial voltage gain. The nine-pin tube is listed by Ray Tubes under the 12AX7, ECC83, and CV4004 designations.
Ray Tubes hand-selects and tests its SELECT tubes, and the gold-plated pins help resist corrosion at the socket contacts. It has controlled bass, clear treble, and a layered midrange. Its presentation brings attention to the texture of vocals and strings and the placement of instruments in the soundstage.
We offer the SELECT 12AX7 in sets of two or four. Each package includes a handbook with burn-in guidance and a certificate of authenticity and warranty.
