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
