Maintained in June 2022! YAMAHA's heavyweight premain amplifier. The low frequency with good damping by a good power transformer and the clear sound typical of YAMAHA are attractive. The PHONO input is equipped with MC, making it a great specification for analog fans. The pre-main part can be separated, and there is potential for development into a separate part. There is peeling veneer, line damage, and cloudy rear panel (Daiki Goto)
