AI-assisted summary
Description from the seller
The Sansui C-77 is a vintage stereo preamplifier from the early 1980s (typically 1980–1981), known for its distinct "SuperCompo" styling and wide range of control options. It was originally designed to be paired with the Sansui B-77 power amplifier, but can work with any other amp.
Features & Design
Phono Support: Built-in phono stage supporting both Moving Magnet (MM) and Moving Coil (MC) cartridges.
Tone Controls: Includes bass and treble adjustments, with the unique ability to select turnover frequencies (e.g., 100Hz for bass) to shape the sound more precisely.
Visual Interface: Features an array of knobs, flip switches, and a color display for source transfer, giving it a tactile "instrument-like" feel often compared to vintage aviation or military gear.
