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.

2 ADJUSTMENTS AND CHECKS
調��確�
2-1 MECHANICAL ADJUSTMENT
2-1-1 Wow and flutter (playback method)
In both FWD and REV play modes, these measurements should be made at the beginning, middle, and the end of the tape. 1. Connect a wow-and-flutter meter to the LINE OUT. 2. Load and play a TEAC MTT-111N test tape. 3. Check that the readings on the wow-and-flutter meter is within 0.19% (JIS WTD).
