This is an auction for a SONY TC-3000SD AC-12. This item was stored in my grandfather's warehouse. I confirmed its operation on 2025/05/20 using AC-12. I confirmed tape playback from the main unit's LINE OUT. Sound came out normally from the headphone jack. Fast forward and rewind functions worked. The DOLBY NR knob is working. The other knobs either showed no change or were not confirmed. Recording function has not been confirmed. The cassette deck lid is damaged. There is a rattling sound from inside, so I believe there are pieces of the lid inside. The minimum and maximum positions of the recording level dial seem to be misaligned. The exterior is in good condition as it was stored in its dedicated case. I will not be offering a dedicated listing for this item.
