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.).

RESET CIRCUIT
When batteries are set or an AC adapter is connected, the reset IC provides a low pulse to the CPU. The CPU then initializes its internal circuit. When the power switch is pressed, the CPU receives a low pulse of POWER signal. The CPU provides APO signal to the power supply circuit and raises RESET signal to +5 V to reset the DSP, the key controller and the gate array.
