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
