Pioneer SX-1300 Back Sockets
The Pioneer SX-1300 back sockets include phono inputs for connecting a record player. The speaker connectors allow for two banks of speakers. It is a very basic set of input/outputs for an early amplifier but enough for an entry level system. This particular unit had been stored in the shed and consequently the RCA sockets are tarnished. The mains wire was also badly corroded and needed replacing.
