 ;
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.

SECTION 5 ELECTRICAL ADJUSTMENTS
Precautions for Adjustment 1. Before beginning adjustment, set the equipment to service mode. After the completion of adjustment, be sure to reset the service mode. For more information, see �Service Mode (service program) � on page 8. 2. Perform adjustments in the order given. 3. Use YEDS-18 disc (Part No.: 3-702-101-01) unless otherwise indicated. 4. Power supply voltage requirement: DC2.5 V in battery terminal VOLUME knob : Minimum RESUME switch : OFF ESP switch : OFF AVLS switch : NORMAL HOLD switch : OFF Before Beginning Adjustment Set the equipment to service mode (See page 8) and check the following. If there is an error, repair the equipment. � Checking of the sled motor 1. Open the upper panel. 2. Press the + and = keys and check that the optical pickup can move smoothly without sluggishness or abnormal noise in innermost periphery n outermost periphery n innermost periphery + :The optical pick-up moves outwardly. = :The optical pick-up moves inwardly. � Checking of focus searching 1. Open the upper panel. 2. Press the ^ key. (Focus searching operation is activated continuously.) 3. Check the object lens of the optical pick-up for smooth up/ down motion without sluggishness or abnormal noise. 4. Press the p key. Check that focus searching operation is deactivated. If not, again press the p key slightly longer. VCC Adjustment Adjustment Procedure:
digital voltmeter (DC range) MAIN board TP401 (VCC) (See page 11) + �
Focus bias Check Condition: � Hold the set in horizontal state. Check Procedure:
oscilloscope (AC range) MAIN board TP522 (RFO) TP520 (VC) (See page 11) 2k�
+ �
1. Set the equipment to service mode stop state. (See page 8.) 2. Connect the oscilloscope to the test point TP522 (RFO) of the MAIN board. 3. Move the optical pick-up to the center by pressing the + and = keys. 4. Put the disc (YEDS-18). 5. Press the ^ key. From focus searching, focus is turned ON while entering CLV drawing-in mode. Tracking and sled are turned OFF. 6. Press the PLAY MODE key. (Both tracking and sled are turned ON.) 7. Check the oscilloscope waveform is as shown below. A good eye pattern means that the diamond shape (�) in the center of the waveform can be clearly distinguished. RF SIGNAL REFERENCE WAVEFORM (EYE PATTERN)
VOLT/DIV : 200 mV (With the 10:1 probe in use) TIME/DIV : 500 ns
RF level 1.0 ± 0.2V
To watch the eye pattern, set the oscilloscope to AC range and increase the vertical sensitivity of the oscilloscope for easy watching.
8. Stop revolving of the disc motor by pressing the p key. 9. After the completion of adjustment, reset service mode. (See page 8.) Check Location: MAIN Board (See page 11.)
1. Set the equipment to service mode stop state. (See page 8.) 2. Connect the digital voltmeter to TP401 (VCC) of the MAIN board. 3. Adjust RV401 on the MAIN board so that the reading on digital voltmeter goes 2.75± 0.05 V. 4. After the completion of adjustment, reset service mode. (See page 8.) Adjustment Location: MAIN board (See page 11)
