Luxman C-02 Preamplifier Champaign Elevate your audio system with the Luxman C-02, a masterfully engineered vintage preamplifier from Luxman’s golden analog era. Designed with the proprietary Duo-Beta Circuit/S, this preamp delivers an exceptionally pure, single-stage amplification path, minimizing distortion while preserving musical nuance and clarity. Built for the discerning audiophile, the C-02 features a built-in step-up transformer for high-gain MC (moving-coil) cartridges, making it a dream for serious vinyl enthusiasts. Its phono section handles both MM and MC with finesse, and a “Phono Straight” bypass switch allows for uncolored, tone-control-free playback when you want absolute fidelity. Other premium touches include LED-based bias stabilization (instead of conventional diodes), gold-plated input/output connectors for low-noise contact, and a warm-up indicator to ensure stable analog performance. In addition, the C-02 supports dual tape monitoring, tape dubbing, subsonic filtering, mono/stereo switching, and tone control with selectable turnover frequencies — giving you flexibility and professional-level control. The chassis is sleek yet robust, with genuine Class-A operation for that warm, distortion-light Luxman sound. Finished in an elegant champagne front, it’s not only sonically refined but visually timeless. If you’re looking to build or restore a high-end vintage stereo rig, the Luxman C-02 remains a benchmark preamp — a superb blend of engineering precision, analog warmth, and audio sophistication. --- Technical Specifications Here are the key technical specs for the Luxman C-02 (based on the original service/manual data): Specification Value Type Stereo preamplifier (Separate) Circuitry Duo-Beta Circuit/S, single-stage, Class A Production Years ~1983–1985 (some sources up to 1987) Country of Manufacture Japan Front Panel Finish Champagne Inputs Phono MM, Phono MC, Line (Tuner), Tape (monitor) Input Sensitivities - MC: 0.1 mV - MM: 2 mV - Line: 130 mV Input Impedances - MC: switchable (approx. 0.04 / 0.1 / 0.3 kΩ) - MM: ~50 kΩ - Line: ~150 kΩ Frequency Response 10 Hz – 100 kHz (line) Total Harmonic Distortion (THD) 0.005% Signal-to-Noise Ratio - MC: ~77 dB - MM: ~90 dB - Line: ~108 dB Outputs - Pre Out: 1 V typical, up to 18 V max - Rec Out: ~130 mV Tone Control Bass ±10 dB (turnover at 200/400 Hz), Treble ±10 dB (turnover at 2/4 kHz) Other Features Subsonic filter, low-boost switch, mono/stereo switch, dual tape monitor/dubbing, tone bypass (“Phono Straight”) Physical Dimensions 453 mm (W) × 81 mm (H) × 315 mm (D) (or approx.)
