Historical Context

The Marantz Model 120 was introduced in the late 1960s, a period of explosive growth for high-fidelity stereo components. It arrived after the legendary and esoteric Model 10B, providing a more practical and affordable FM tuner solution for a broader market. Its significance lies in its role in bringing the Marantz name and its associated quality into more living rooms. During this era, FM broadcasting was maturing, with more stations offering high-quality stereo programming, and the Model 120 was a component perfectly timed to capture that market. It helped solidify Marantz's reputation not just as a maker of exotic statement pieces, but also of excellent, reliable mainstream components.

Design Features

The Model 120 features the classic Marantz design language of the era: a substantial brushed aluminum faceplate dominated by a large, blue-backlit tuning dial with a smooth flywheel tuning action. The layout is clean and functional, with a centrally placed signal strength/tuning meter and a prominent stereo indicator lamp. Build quality is excellent, with a heavy steel chassis that provides shielding and reduces microphonics. The walnut wood side panels integrate seamlessly with other Marantz components for a unified rack look. A key feature is its Phase-Locked Loop (PLL) stereo decoder, which was a modern advancement for its time, providing stable and quiet stereo reception with good separation. The inclusion of both fixed and variable audio outputs offered flexibility in connecting to various amplifiers.
