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.

(3) Press the channel buttons (+, �) simultaneously to enter the manual tracking mode. This also brings tracking to the center (centre). (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) Press the channel buttons (+, �) simultaneously to enter the manual tracking mode. This also brings tracking to the center (centre). (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.
