I'm happy. Good quality. Very helped me with my work..............................
;
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.

CD CLOCK ADJUSTMENT PROCEDURES
(All segments on FL tube light on) 3. Adjust trimmer capacitor C703 so that the reading of frequency counter becomes 524.288 kHz 1Hz.
Preparation 1. Connect frequency counter to the terminal TP01 on main PC board (NAAR-6875) Set trimming resistors R123 to center. 2. Press and hold down MEMORY button , then press the DISPLAY button.
Focus gain adjustment 1. Set output of the audio oscillator to kHz and 1 1.5 VP-P 2. Connect the oscilloscope and audio oscillator as shown below. (Refer to Fig-1) 3. Load test disc YEDS-18 on tray and play the track 2. 4. Adjust trimming resistor R123 so signal 2 on the oscilloscope becomes 1.25 times of channel 1. (Refer to Fig-2)
