The Sony STR-212S FM/AM Program Receiver (late 1970s) is a vintage solid-state stereo receiver with about 15W per channel into 8Ω, FM/AM tuner, phono/tape/aux inputs, bass & treble controls, loudness, and headphone output. Its unique “Program Sensor” feature lets you place markers on the dial—radio stays muted until the pointer hits a marked station (a manual station-preset system). Compact, lightweight (~5 kg), and best suited for small to medium rooms with efficient speakers.
