I do not have very much to say.
The price is quite covenient, delivery was better as promised (about 12 ours, against the specified 24 hours if I remember well), and the quality of the PDF is more than acceptable.
The Service Manual of Sansui R30 itself is also satisfactory: good graphic for schematics and layouts, simple and well structured.

Happy to find finally a schematic for this amplifier. The schematic is of good quality, the pcb layout is useless: all is black. Never the less, it is very easy to find the components on the board using the schematics.

Hard to find manual was ready the next day. Scans were very legible (including schematics). All the essential parts of the service manual were present (adjustment procedure, schematics, and parts list). It would have been nice if the rest of the manual was included (disassembly procedure, theory of operation, etc.).

The Service Manual for the Kenwood KR-V55R provided by owner-manuals.com was as described/advertised. The contents provided the necessary information to effect a diagnosis of the unit. The schematics above all else was instrumental in tracing the the signal flow from component to component.

This manual was the factory original. Excellent value and contained all the details I needed. Easy dowwnload provided the information when I needed it.
After replacing the pickup, set the unit in the service mode to display a jitter value on the LCD. Confirm that the jitter value measured with a jitter meter is within 12% of the jitter value displayed on the LCD. If it is within 12%, then adjustment is not necessary. Please note that a jitter value displayed on the LCD is hex data. Refer to the corresponding decimal notation value using the Jitter Conversion Table and confirm it with the measured value. Fix the screws "a", "b" and "c" with screw lock paint.
If the measured jitter value is outside the 12% tolerance range, perform the following adjustments.

Jitter value adjustment procedure (Pickup horizontal level adjustment relative to the DVD recording surface) (For the adjustment tool use a 3 mm wrench and not a screwdriver, this procedure will make the adjustment easier.)
3 mm wrench
(1) Set the unit to the service mode and display a jitter value (hex data) on the LCD. (2) Turn each of the screws a, b and c, by a half-turn per step, in the direction that reduces the jitter value in order to minimize it. (Do not turn a screw more than a half turn at a time, but adjust the screws in the cycle of a � b � c � d � a.) (3) After completing the adjustment, secure the screws with screw lock paint.
