 ;
got exactly what i ordered in a very timely manner. will use again for other manuals
 ;
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.

Testing Performance To test the voltage measurement accuracy (oscilloscope)
Acquire the data
Use the following table for steps 1 through 5. Oscilloscope Settings
V/Div 4 V/Div 1 V/Div 400 mV/Div 40 mV/Div 40 mV/Div 400 mV/Div 1 V/Div 4 V/Div Offset -7.0 V -1.75 V -700.0 mV -70.0 mV 70.0 mV 700.0 mV 1.75 V 7.0 V Supply -14.0 V -3.50 V -1.40 V -140.0 mV 140.0 mV 1.40 V 3.50 V 14.0 V
Voltage Readings
Upper Limit -13.7 V -3.43 V -1.37 V -137.0 mV 143.0 mV 1.43 V 3.57 V 14.3 V Lower Limit -14.3 V -3.57 V -1.43 V -143.0 mV 137.0 mV 1.37 V 3.43 V 13.7 V
1 Set up the oscilloscope according to the table above. a Press the Chan key. b Move the cursor to the V/Div field, then use the RPG knob to dial in the V/Div values shown on the first line of the table. c Move the cursor to the Offset field. Use the front-panel keyboard to enter the offset value shown on the first line of the table. Use the left and right cursor-control keys to select either mV or V. 2 Acquire the zero input voltage. a Disconnect the power supply from the channel input. b Press the blue shift key, then press the Run key. Wait for approximately five seconds (averaging complete), then press Stop. c Press the Markers key. Move the cursor to the Va Volts field. Using the RPG knob, move the Va marker over the oscilloscope trace on the display. 3 Acquire the measured voltage. a Connect the power supply to the channel input. Set the power supply voltage according to the first line of the table above. b Press the blue shift key, then press the Run key. Wait for approximately five seconds (averaging complete), then press Stop. c Press the Markers key. Move the cursor to the Vb Volts field. Using the RPG knob, move the Vb marker over the oscilloscope trace on the display. d Record the voltage in the Va to Vb field in the performance test record. 4 Repeat steps 1 through 3 for the second line of the table, then for the rest of the lines
of the table for channel 1. 5 Repeat from "Set up the logic analyzer" for channel 2, replacing channel 1 with channel 2 where applicable.
