thank u so much for this manual that was so cheap that i thought it was a scam but i gambled anyway because it was too good of a deal to pass up and behold,the manual has everything and details of everything even the screws and im still amazed and very happy with my manual .so take my word and jump on it before they realize how cheap they selling thier manuals..thank you so much for taking time to read my thoughts

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.

(9) Neither picture nor sound is output * Cannot search a) Can the feed system be driven? Check the waveform of TRSDRV signal (R273). --- Waveform between R274 and C271.
Search results in a change of duty (three values with 2.5V at the center) (The figure is exaggerated.) Check the waveform of CN101 "1" and "2". --- After the driver (IC271)
Approx. 2.5V
For short-distance search, the waveform becomes roundish, not trapezoidal, and voltage is low.
b) Is kick available? Check the TRDRV signal waveform from R289.
Check the waveform of CN101 "22" and "23" --- After the driver (IC271) Although differs in amplitude and DC offset, the waveform is similar to that of R289
Long-distance seek Feed
Tracking
Kick pulse
Acceleration pulse at start; deceleration pulse at stop (each one) (In the direction of search, opposite to this figure)
Kick pulse (fine seek) is inserted after longdistance seek. (Not one)
Hold (DC) during feed
