Marantz ST 500, SD3510, PM 750 DC

Overview

This matched Marantz system combines the PM750DC integrated amplifier, ST500 AM/FM tuner, and SD3510 cassette deck into a complete early-1980s separates stack. Together they represent the slimmer, more modern Marantz design language that followed the company's famous 1970s receiver era.

The centerpiece is the PM750DC, rated at 80 watts per channel into 8 ohms. It includes both moving-magnet and moving-coil phono capability, making it unusually flexible for a system of its period. The ST500 adds digital AM/FM tuning, while the SD3510 is a two-head cassette deck compatible with normal, ferrichrome, chrome, and metal tapes.

Why This System Matters

Vintage Marantz is often reduced to the large silver receivers of the 1970s, but systems like this show how the brand evolved into the 1980s. The PM750DC retained substantial output power and broad analog connectivity while adopting a lower-profile component format. Keeping the amplifier, tuner, and deck together also preserves the visual coherence these pieces were designed to have as a system.

Who It's For

Ideal for someone who wants a coordinated vintage system rather than assembling unrelated separates. It offers enough amplifier power for many full-size speakers, dedicated vinyl capability, radio reception, and cassette playback and recording in one period-correct Marantz stack.
