SPEED HOLE                
                                
                                          
 TURN YOUR WALKMAN  LIKE A TURTLE.  THERE 
 MIGHT  BE  SOMETHING  THERE  THAT  LOOKS 
 LIKE  A  SCREW HOLE  BUT IT COULD  BE  A 
               SPEED HOLE.                
 THE  RULE   IS  IF   YOU  CAN'T  GET   A 
  REASONABLY SMALL SCREWDRIVER IN THERE,  
          IT'S NOT A SCREW HOLE.          
                                          
                  USAGE                 
                                          
 USE  THE SPEED  HOLE  LIKE A SCREW  HOLE 
       BUT WITH A TINIER SCREWDRIVER      
                                          
                  THIS                  
                 ADJUSTS                
                   THE                  
                 PITCH                
                                          
 SOME CASSETTE PLAYERS HAVE  SPEED SCREWS 
 BUT NO HOLES FOR THEM. TO  GET  TO THOSE 
 SCREWS  YOU  NEED  TO   DISSASEMBLE  THE 
 WHOLE   THING.   COULD   BE   WORTH   IT
