I PURHASED THIS PRODUCT BECAUSE I WAS HAVING PROBLEMS WITH MY CDR20 HARMAN KARDON RECORDER. WHICH I PURCHASED NEW 12 YEARS AGO. AFTER REVIEWING THE MANUAL, I WAS ABLE TO ADJUST THE TENSIONER IN THE SYSTEM. WORKS LIKE A CHAMP!.
SAVED ME AT LEAST 100.00 WHICH WAS WHAT A SERVICE REPAIR STATION WANTED. GREAT MANUAL EASY TO READ. SPECIALLY AFTER I PRINTED THE PAGES WHICH DEALT WITH MY RECORDER. THANKS A LOT!!!!!!!!
