- Description
- Specifications
The 6SR7 is a duplex-diode medium-gain triode vacuum tube designed for detector, automatic volume control (AVC), and audio driver or voltage amplifier applications in radio receivers. Units are available in both new old stock (NOS) and tested used conditions. Manufactured by companies including RCA, Sylvania, GE, and Raytheon, these tubes feature a 6.3V filament rating and an octal base design in a metal envelope. Used for servicing vintage radio chassis, broadcast receivers, and audio signal processing circuits requiring detector capability combined with moderate voltage amplification.
