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.

Procedure : 1. Connect the oscilloscope to TP (RFACO) and TP (VC) on the CD board. 2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01) 3. Press the [CD NX] button. 4. Confirm that the oscilloscope waveform is as shown in the figure below. (eye pattern) 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: 0.2 V (with the 10: 1 probe in use.) TIME/DIV: 500 ns
in phase 45° good
90° 135° 180° wrong
4. After the adjustments, apply suitable locking compound to the parts adjusted. Adjustment Location:Record/Playback/Erase Head Tape Speed Check Mode: Playback

When observing the eye pattern, set the oscilloscope for AC range and raise vertical sensitivity.

1. Insert the WS-48B into the deck. 2. Press the N button on the deck. 3. Confirm that the frequency counter reads 3,000 ± 90 Hz. Sample value of Wow and Flutter: 0.3% or less W.RMS (JIS) (WS-48B)
CD SECTION
Note: 1. CD Block is basically constructed to operate without adjustment. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10 M� impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. 5. Check the focus bias check when optical block is replaced.
