Sony TC-RX77ES Dolby HX Pro Cassette Recorder

Cosmetically in quite nice shape, just a bit of scuffing/scratching that you can see in photos.

Powers on and lights up, then makes a screeching sound.  Also makes a screeching sound when you try to open/eject the tray or click "stop".  I've included a video to show this behavior.  I have not been able to test any further.  I opened it up and see that there's at least one missing belt, I assume it disintegrated/broke.  I have not done anything to it aside from taking the top off and putting it back on.  I'm not at all technologically inclined and don't have the time.  Sold as-is, untested, with no returns.
