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.
4 Alignment and Adjustments
CONFIDENTIAL
Run the All Mode save in the Right Menu. Caution : Do not Run the All mode Save at the other scannig times except for 1024x768 (68kHz/85Hz). 4-2-3 (b) VERTICAL SIZE ADJUSTMENT CONDITIONS Scanning frequency: Display image: Brightness: Contrast: 68 kHz/85 Hz Crosshatch pattern Maximum Maximum
4-2 Display Control Adjustments
4-2-1 HIGH VOLTAGE
Signal: 1024 x 768 (68 kHz/85 Hz) Display image: Don�t care Contrast: Minimum Brightness: Minimum Limit: 26.0 kV ± 0.3 kV Measure the high voltage level at the anode cap. High voltage should be within the limit as above.
4-2-2 CENTER RASTER
Adjust SW401 so that the back raster comes to the center when you apply basic mode for 17�.
4-2-3 Centering
Centering means to position the center point of the display in the middle of the display area. Horizontal size and position and vertical size and position control the centering of the display. Adjust the horizontal size and vertical size to their optimal settings: 312 mm (H) x 234 mm (V). Adjust the horizontal position and vertical position to � 5.0 mm of the center point of the screen. |A-B| � 5.0 mm.
C
Use control bar after selecting �V-SIZE� in left menu to adjust the vertical size of the display pattern to 234 mm.(Tolerance: ± 4 mm.) 4-2-3 (c) HORIZONTAL POSITION ADJUSTMENT CONDITIONS Scanning frequency: Display image:
68 kHz/85 Hz Crosshatch pattern
Use control bar after selecting �H-POSITION� in left menu to center the horizontal image on the raster. 4-2-3 (d) VERTICAL POSITION ADJUSTMENT CONDITIONS Scanning frequency: Display image: 68 kHz/85 Hz Crosshatch pattern
|C-D| � 5.0 mm.

Use control bar after selecting �V-POSITION� in left menu to center the vertical image on the raster.
Figure 4-3. Centering * In Softjig window, �Geometry� has to be selected for GD adjustment. 4-2-3 (a) HORIZONTAL SIZE ADJUSTMENT CONDITIONS Scanning frequency: Display image: Brightness: Contrast: 68 kHz/85 Hz Crosshatch pattern Maximum Maximum
4-2-4 Linearity
Linearity affects the symmetry of images as they appear on the screen. Unless each row or column of blocks in a crosshatch pattern is of equal size, or within the tolerances shown in Tables 4-2 and 4-3, an image appears distorted, elongated or squashed. Table 4-1. Standard Modes Linearity: 1024x768/85Hz
Standard Modes Linearity Difference between Each block (8 %) adjacent blocks (4 %) 4:3 Horizontal: 20.9~23.1 Horizontal: Less than 0.88 mm Vertical : 20.9~23.1 Vertical : Less than 0.88 mm
Click Standard Dump on the right Menu in the general field. Use control bar after selecting size B+ in the left Menu to adjust the horizontal size of the display, Pattern to 312mm(Tolerance : ±4mm.)
