Popular Sony model. Thanks to the Clear Voice function, the sound quality is good for its small size. Uses two AA batteries. It works with all the basic functions: record/playback, fast forward/rewind, counter, speed control, 2x mode, pause, headphone jack, VOR (voice-activated recording, stops a little after the sound ends), etc. The belt has been replaced with a high-precision one and the speed has been adjusted. There are scratches and dirt overall, and there is a stain on the side as shown in the third photo. It has been wiped with alcohol, so it feels smooth. Cassette tape recorders are still convenient, so please consider it. Can be combined with other items. Please comment in advance as it will be cheaper. If you have a broken tape recorder, I can repair it. Please see my profile. The following are common notes for used tape recorders: ・This is a product from 20-30 years ago. Performance may not be the same as new. Please handle it carefully as it is more likely to break down than a new one due to deterioration of parts. ・The surface has been wiped with alcohol, but there may be stains that cannot be removed or overlooked. ・When you receive it, insert batteries and press the play button before inserting a tape to make sure the spindle rotates. ・If it doesn't rotate, check the pause function. Also, try new batteries (pay attention to the battery orientation). Furthermore, press each button one by one. ・Next, insert a tape and press the play button to check if the tape rotates and sound comes out. If it doesn't rotate, the tape is likely the cause. ・Old tapes may not run smoothly. In that case, rewinding the tape may help. ・If the tape rotates but there is no sound, check the volume. If the pitch is off, check the 2x mode and speed control. ・If you turn up the volume too high, the sound will distort. 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. ・Leaving the batteries in may cause leakage. I have seen many tape recorders with internal corrosion. Please remove the batteries if you are leaving it for a month.
