Welcome to IOU Digital Library

A practical high-fidelity MOSFET audio amplifier project delivering 2 × 50 W output. The article presents schematic diagrams, component lists, PCB/assembly notes and measured performance aimed at hobbyists/audiophiles. It reads like a magazine construction project (detailed build notes and circuit explanation) rather than a textbook. Related MOSFET 50 W / 2×50 W schematics and articles from the same era (e.g., “Playmaster” 50W+50W MOSFET designs) show similar layout, protection and biasing approaches.
