Internal and external maintenance has been applied and brushed up. The vivid sense of dynamism and the sharpness of the high frequencies typical of YAMAHA have been revived. It has a low frequency thickness that 1000 monitors don't have. It is a timeless masterpiece with a clear sense of transparency, upper and lower driving force, and the smooth connection, and the heavy exterior with an ebony finish that stands out at a glance even today. It is in good condition due to maintenance. Serial 11478L 11478R (Yamato Yuki)

Network maintenance (Since the terminals have already been replaced with external products, adjust the direction and tighten, apply a screw fastener, and replace the mounting screws. ATT contact status check (check that there are no gaps). A frequency characteristic measurement check (~ 42 kHz) was performed, and the original capacitor was continuously used because the results were good. Input/output waveform and balance check, sound output check) Unit detachable)
