SONY cassette player with voice recorder function. It can play, fast forward, rewind, and auto-stop. Sometimes the rewind function doesn't work, which I think is due to aging. Holding the button down firmly usually restores the rewind function. It plays in mono. I have never recorded with it. No DC adapter included. I think it's in good working condition. - Brand: SONY - Model: Cassette Player - Features: Voice Recorder - Connection Terminals: Headphone Jack - Operation Buttons: Play, Record, Stop buttons - Strap: With strap Counter works.
