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
