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 are a lot of front panel stains on the exterior. There is deterioration on the back side of the wood panel (Sasaki Shota)
