A standard tape recorder from audio manufacturer Aiwa. Uses two AA batteries. Although the brand is Aiwa, it's made by Sony. The speed switch is missing, so it only operates in 2x mode. As indicated on the front sticker, a 90-minute tape can be used for 3 hours. Recording/playback, fast forward/rewind, speed control, voice activation (starts recording when sound begins, stops after a while when there's no sound), counter, and an earphone jack all function. The belt uses a high-precision component with minimal eccentricity (uneven rotation), and the speed has been adjusted. There are few scratches or stains, and the overall appearance is clean. It has been wiped with alcohol, so it has a smooth feel. Cassette tape recorders are still convenient, so please consider this one. Please note that this is a used item, so its performance is not equivalent to a new one. Old tapes may not run smoothly. In that case, rewinding the tape may help. Can be shipped with other items (will be 200 yen cheaper, so please comment beforehand).
