Exactly the JVC service manual and schematics that I was looking for - delivered just hours after order. Will do business again!

This is a fantastic site, ad I have been a returning satisfied cusumer!
Thanx for a great sevice!

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.

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!

Well done!!! I found what I need to have, indeed!
Furthermore, due to my hobby is repairing vintage equipments, I added this web site in my desk toolbar because I have in mind to search further service manuals. Thanks a lot www.owner-manuals.com !

(4) Adjust the AUDIO OUT waveform and Control pulse waveform by turning the screws (1), (2) and (3) little by little until both waveforms reach maximum. The screw (1) and (3) are for adjustment of tilt and the screw (2) for azimuth.

(1) Play back the alignment tape (A1). (2) Apply the external trigger signal to D.FF (E), to observe the V.PB FM waveform at the measuring point (D). (3) Set the VCR to the manual tracking mode. (4) Loosen the screws (4) and (5), then set the A/C head positioning tool to the innermost projected part of the A/ C head. (See Fig. 2-3-3a.) (5) Turn the A/C head positioning tool fully toward the capstan. Then turn it back gradually toward the drum and stop on the second peak point position of the V.PB FM waveform output level. Then tighten the screws (4) and (5). (6) Perform the tracking operation and make sure that the V.PB FM waveform is at its maximum. If it is not at maximum, loosen the screws (4) and (5), and turn the A/C head positioning tool to bring the A/C head to a position, around where the waveform reaches its maximum for the first time. Then tighten the screws (4) and (5).
(1) Play back the alignment tape (A). (2) Apply the external trigger signal to D.FF (E), to observe the AUDIO OUT waveform and Control pulse waveform at the measuring points (D1) and (D2) in the ALT mode. (3) Set the VCR to the manual tracking mode.
