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
