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
