The 7E7 is a combined twin-diode and remote-cutoff pentode vacuum tube designed for AM detection, automatic volume control (AVC), and RF or IF amplifier service in radio receivers. Featuring a 6.3V filament rating and an 8-pin lock-in (loctal) base in a glass envelope construction, it consolidates signal detection and variable-gain RF/IF amplification into a single envelope. Manufactured by companies including Sylvania, Philco, RCA, and GE, this tube was utilized in mid-century radio chassis and automobile receivers requiring compact, multi-purpose circuit designs.
