Every corner has been maintained, such as replacing 89 deteriorated capacitors and disassembling and cleaning each switch! SONY's name control amplifier. The sound field that spreads without stuttering is unique to the 70s SONY brand. The feeling of extrusion in the middle range and the sense of dynamism that radiates throughout the entire range are exquisite. As for the exterior, there is eccentricity in the input switching SW, and there are also dullness and small scratches. Serial 2016 23 (Matsumoto Tsuyoshi)
