Maintenance has been completed, including dismantling and cleaning the main volume and replacing 30 transistors! The first α907 model. It has the best power and amount of information in the same series. The unique α-X balance circuit achieves a high signal-to-noise ratio. While it has the strength typical of Sansui, the sound is clear and allows you to clearly feel the outline is attractive. There is a small scratch (Daiki Goto)
