Hello friends need some help on this candle jtr- 1287 cassette mechanism .I tore into this seeing someone else did "some" work on it and was not working right at first the buttons where hard to push but did work .I also noticed that the tape head would not return back to starting position when stop was pressed I had to manually push it with my finger to return the rest of the way. So I need some pictures of the front cassette mechanism down by the buttons I also see that there is a spring put on there I believe to help aid return of the whole play head but just seems to have some tension but not even sure if it goes there? Im not too sure what makes the whole tape head assembly return back to its original spot i know there is the one spring attached to the pinch roller that helps it rise up and if some break it wont fully play.Any help would be appreciated.
