exactly as they say. Within 24 hours the link to the pages and offcourse it was the right service manual. Super and thanks
The manual was exact the thing that was promised. My old car stereo is working again thanks to the information supplied.
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!!!!!!!!
You can fully trust on this one!
All the schematics are very crear an in one piece per page
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.
