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!!!!!!!!
I have never bought a service manual which is as competely readable as this althogh it was a scanned pdf. Thank you for this succesful manual also cheaper than other sites.
Thanks for a very good and readable servicemanual. Just what I needed as a "dinosaur technician". I really recommmend this site and will come back.

The manual I purchased was just what I needed. I was glad to find a site where I can find so many manuals on a wide variety of products.
