Miracle! Fully restored and serviced! Fully functional, super beautiful! This is a Sansui integrated amplifier AU-607X. The exterior is in miraculously beautiful condition. Functionally, I have confirmed sound output from each output. Sound is produced evenly on both left and right channels, with no distortion in sound quality. It produces the delicate and soft sound characteristic of Sansui. Maintenance performed by a professional audio technician includes replacement of faulty parts, volume replacement, disassembly and contact cleaning of switches, and alcohol cleaning. It is in very good condition.
