WAITING WITHOUT WAITING LXXIII: first the structure of cassette

I found the image here. 

What is/was wrong with the vs cassette was the POSITION of the PRESSURE PAD. It lies on part of the cassette case. There, the case broke and the PRESSURE PAD did not stay where it ought to. Consequence was that one could hardly hear the songs. So I needed a new cassette case. 

I will post pictures of the broken case and the new one soon.
