 A-8870 ONKYO Service Manual by FREDERIC LIETARD;
Je suis audiophile belge, électronicien et créateur d'enceintes acoustiques. J'ai apprécié la qualité des documents fournis. Ils sont très lisibles, ils peuvent être agrandis sans problème et ils sont complets. Pour moi, c'est parfait. Pour cette qualité, je suis d'accord de payer. Et le système de paiement et d'envoi est simple. Merci, continuez comme cela. Frédéric
 T7 SANSUI Service Manual by Gary Ramey;
The cover page was a little scary, very dark but readable. The remainder of the document was better copy and easily readable. Why would I give 5 Stars? (1) PRICE, (2) AUTHENTICITY, It was the real deal, filled with service information, including the specific information I required. (3) PRIVACY, I didn't start to get slammed with spam. (4) EASY TRANSACTION. Painless. (5) COMPLETE, I have found several manuals here, that I could find nowhere else. (6) I will be a repeat customer!
