This item was stored in my uncle's house's warehouse. The basic functions of recording, playback, rewind, fast forward, and sound output have been tested. Recording was also possible via CD direct. However, I have forgotten how to adjust the bias, so it has not been confirmed. Tape speed and azimuth were checked with free software, but please understand that this is not a precise measuring instrument. Please be aware that there are scratches, rust, and unremovable stains. No returns or claims accepted.
