All functions worked without any issues, including cassette playback, fast forward/rewind, auto reverse, track start, AM/FM radio, and speaker output.
The LCD display is a little hard to see in the photo, but it is easier to see in person than in the photo.
We have performed maintenance, including replacing the cassette drive belt with a new one, cleaning the head, adjusting the cassette mechanism, replacing the leaking capacitor with a new one, and repairing solder cracks, and many other things, so it is in good working order.
