6SN7 Vacuum Tube – Octal Dual-Triode for Hi-Fi Preamp & Headphone Amps

The 6SN7 is an octal dual-triode prized for its large glass envelope, low microphonics, and warm, spacious tone in gain and phase-inverter stages.

• Tube type: Dual triode
• Base: Octal 8-pin
• Heater: 6.3V AC, 0.6A
• Typical use: Preamp gain and phase-inverter stages in hi-fi amplifiers, headphone amps, and DACs

A long-standing favorite for tube-rolling hi-fi builders looking for a bigger, rounder sound than 12AX7-family triodes.
