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
