This is a high-performance model with auto-reverse, based on Sony's popular TCM-400. You can listen to the B-side of the tape without flipping it over. It produces good sound despite its small size, thanks to the clear voice function. Uses two AA batteries. It functions as expected: record/playback, fast forward/rewind, speed control, counter, auto-reverse, 2x mode, and an earphone jack. The belt has been replaced with a high-precision one and the speed has been adjusted. The exterior has almost no scratches or dirt, and the gloss is like new with a smooth feel. Cassette recorders are still convenient, so please consider this one. Test batteries are included. Auto-reverse drains the batteries a little faster, so using an AC adapter is recommended. The genuine AC-E300 (pictured in the 7th photo) is included. Can be combined with other items (200 yen discount). Please comment beforehand. If you have a broken cassette recorder, I can repair it. Please see my profile. The following are common notes for used cassette recorders: ・These are items from 20-30 years ago. Performance is not necessarily equivalent to new. Please handle them carefully as they are more likely to break down than new ones due to deterioration of parts. ・The surface has been wiped with alcohol, but there may be some stains that cannot be removed. ・Upon arrival, please press the play button to confirm that the spindle rotates. ・If it doesn't rotate, check the pause function. Also, pay attention to the battery orientation. Then, press each button one by one. ・Next, insert a tape and press the play button to check if the tape rotates and sound is produced. If it doesn't rotate, the tape may be the cause. ・Old tapes may not run smoothly. In that case, rewinding the tape may help. ・If the tape rotates but no sound is produced, check the volume. If the pitch is off, check the speed control. ・The sound will distort if you turn up the volume. The sound volume and quality are not comparable to a large radio cassette player. ・I have checked the main functions, but I haven't been able to check everything. ・If the record button cannot be pressed, the tape's record tab may be broken. You can record by covering the record hole with tape. ・Leaving the batteries in may cause leakage. Please remove the batteries if you are not going to use it for a month.
