The Marantz 3200 is a vintage stereo control console (pre-amplifier) from the mid-1970s. It features two inputs for turntables, tuner, and tape decks, a three-band sliding EQ for precise tone control, and a pre-out that allows it to be used with a separate power amplifier. The 3200 is a popular component for vintage audio systems and is often paired with the Marantz 140 power amplifier. This is a classic, solid-state stereo control console/preamplifier well known for its warm, high-quality analog sound and robust build. It is a highly regarded piece of vintage high-fidelity equipment, often paired with the Marantz Model 140 power amplifier.

This gem was completely rebuilt by DALAUDIO in November of 2025. A complete list of components removed (see photos) and installed will come with the unit> Documentation includes the PCB, part location, device removed /device installed (and upgrades noted). Every board was addressed - Preamp Tone PCB, Relay/Amp Out PCB. Phono Stage PCB, Power Supply PCB. Nichicon Capacitors were used throughout, and all signal BCE transistors were changed. The diodes, and the main power - on relay and components were changed. The unit was then set to service manual spec and fully tested. You may find one that is less expensive, but it will be difficult to find one that has as much effort and attention to detail carefully applied. We will include a copy of the service manual and user manual if you bring an USB thumb drive.

Key Features and User Experience
Source Selection: The Model 3200 is noted for its source selection flexibility, tone control, offering a pure analog sound cherished by audio enthusiasts.
Tone Controls: A standout feature is the three-band sliding equalizer (bass, mid, treble) which allows users to fine-tune the sound to their environment or preference. Reviewers mention this helps in adjusting the tone of specific instruments, such as a piano in jazz recordings.
Sound Quality: Users praise the unit for its "amazing," "incredibly smooth," and "rich" sound. Many reviewers find its audio quality superior to some modern equipment, highlighting the clarity and "airiness" it brings to music.
Speaker Switching: The unit includes a speaker switching feature, which allows users to run multiple sets of speakers, a function less common on separate power amplifiers of that era. The speaker outputs from the power amplifier must be routed back through the preamp for this feature to work, as well as for the headphone output.
Build Quality: The 3200 features a durable brushed aluminum or silver faceplate and a classic design that is highly valued by collectors.
