I have this same boombox. The end-of-tape shutoff did not work well. Once a tape reached the end and the cassette player remained on in the play mode. As a result (when I found it), something (a belt?) broke, because it will not play. So, I too would be interested in info on how to make this repair. If this is a universal problem with this machine, I suppose the manufacturer won't issue a recall unless it poses a risk of injury.
