Refresh maintenance has been completed! The fresh, fresh tone has returned. The tone with a high sense of transparency and texture shows how much Yamaha applied power at that time. The built-in solid state and DC amplifier configuration, can be switched between grade B and grade A, and the eye-catching VU meter is also one of the attractions. The exterior has small scratches and dark spots corresponding to the year. Serial 07799 (Satoshi Yonejima)
