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
