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
