Vintage Sony TCS-310 stereo cassette-corder portable tape recorder, one of Sony’s compact field recorders from the era when cassette recording was everywhere. This unit is being sold as-is and untested because the battery terminal is seized and I wasn’t able to access it to test with batteries. Cosmetically it still has that classic Sony design and these pieces are often picked up by collectors, tape enthusiasts, or people looking for parts or a restoration project. Because of the battery issue it’s being listed as a project unit, so please review the photos closely for the exact condition before purchasing.
