Maintained! This mono power amplifier was developed as the first full-scale high-output power amplifier for consumer use. The sound quality is unique to AccuPhase, which is high power and full of subtlety. Equipped with a digital meter that instantaneously calculates real power. Switching between modes makes it easy to drive even speakers with ultra-low impedance. The exterior is dull and scratched due to aging. Serial K7Y241/K7Y242 (Satoshi Yonejima)
