If the connectors are just dirty, you can clean them with a non-abrasive 
eraser and alcohol.  If they are scratched up, you can put a layer of 
solder on them. If part of the circuit trace is gone, they will have to be 
replaced. They used to make stick-on circuit traces. This was a foil trace 
with glue on the bottom side.  On the cassette connector, the stick-on 
glue will probably not hold up.  You should use super-glue to apply these.

NOTE: On some of the earlier PETs, the top and bottom traces of 
the cassette connector were not connected together. On these I had to 
drill a small hole through the board on each contact, and solder a small 
wire from top to bottom.
