Circuit Project Electronic

This is a small 2*25 (actually, 2*50) WPC amplifier with 3-order crossover stage (configurable as LP or HP). Of particular interest is the unconventional autoformer PS arrangement. Since the power FET’s drains are not tied to ground anymore, it needs another transformer to drive gates. Gate driver is TL494 + MPSW56 followers, powered by REMOTE line.
