Product details

Class A M4 Preamp Board Warm Sound

This is a high-fidelity Class A preamplifier audio board designed for audiophile-grade signal conditioning. Dimensions and weight are not specified in the source material; the board uses a PCB substrate and features a black finish. It incorporates a 58AG92M dual-precision op-amp mounted in a gold-plated socket, delivering warm, tube-like tonal character with rich mid-high frequencies and deep, powerful bass response. The design includes two large integrated heat sinks, additional filter capacitors, balance adjustment capability, and amplification factor conversion support. Power regulation is handled by a TL431 high-precision voltage regulator, ensuring stable, balanced, and constant-current supply to the op-amp — a significant improvement over standard three-terminal regulators. As expected with Class A topology, mild operational heating occurs; this is normal and inherent to the circuit design. Installation is straightforward: connect power and signal cables only — no complex setup required.
