This is the second Manual I have ordered from owner-manuals, I give it five stars because it is exactly what I expected given the age of the equipment. So the contents look a bit aged and the pictures a bit grainy, it fulfills my needs and I am glad I can still get hold of them.

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.).
XL-30V
� Laser abnormal
Is +6.2V on the emitter of Q861? Yes Is +5V on the collector of Q861? Yes Is +5V on the 64 pin (VDD) of IC802? No Yes Is +5V on the 6 pin, the 43 pin and the 51 pin (DVDD) of IC802, the 15 pin (PVDD), the 25 pin (AVDD), the 39 pin (AVDD3)? Yes Is 0V on the 38 pin (SEL) of IC802? No Yes Yes No Check the pattern between IC806 and IC802 (BUCK/CCE/ BUS0-3). Check the parts around IC801 and Q801. If normal, the pickup is defective. Check the PWB pattern among the collector of Q861 and the 6 pin, the 43 pin, the 51 pin, the 15 pin, the 25 pin, the 39 pin of IC801. Does laser light on when cutting the pattern between the 38 pin (SEL) of IC802 and the 8 pin (SEL) of IC801? No No Check the PWB pattern between the 2 pin of BI605B/ CNS605B and the emitter of Q861.
Check around IC804 and Q861.
Check the PWB pattern between IC807 and the 64 pin of IC802.
No
Is approx. 2V on the collector of Q801? No Yes Check BI802/CNS802. If normal, the pickup is defective.
� NO DISC display
Does RF waveform of approx. 1.3V (P-P) appear on the 22 pin (RFO) of IC801? Yes Does eye pattern appear on the 24 pin of IC802? Yes Check around IC802. If OK, IC802 is defective. � The Video CD cannot be played normally. Whilst the disc is playing, is a signal being supplied to pins 96 ~98 on IC15V? (Refer to the waveform shown in Figure 45.) Yes Does the image freeze sometimes? Yes The disc has flaws in it or it is dirty. The disc itself has a defect. The data is faulty. IC804 is defective. No (Not displayed)
2µs / d
No
IC801 or BI801/CNS801, BI802/CNS802 is defective. Or the pickup is defective.
Check around IC801. If OK, IC801 is defective. No
No
IC802 is defective.
