Maintenance has been completed, such as dismantling and cleaning the main volume and disassembling and polishing of each switch! The Sansui MOS FET premain is particularly popular among 907 generations. It is an amplifier that thoroughly pursues circuits, mechanisms, and materials. It has a highly transparent texture unique to MOS, and the mid-high range unique to MOS, which is a bit different from conventional Sansui machines, is attractive. It is an amplifier that has a high overall power and is notable for its beautiful tone. The exterior has scratches and bumps on the top plate, etc. Serial 628036320 (Yonejima Satoshi)
