Quick delivery, the document was usefull, although the copy was i little bit unclear in the details.
A complete and well done copy of the manual, at a not expansive price!
The delivery of the manual is very fast.
Thank you for all
Perfect quality. Was able to fix speed drifting on my Sansui Turntable using the service manual instructions for PLL adjustment.
I am very happy regarding the online purchase of this manual from Owner-Manuals.com as with this I could set right my Denon CD player and Amplifier.
I once again sincerely thank them for the prompt service which was rendered to me.
More than pleased with my prurchase, very good product for the price.
