 ;
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.

Adjustment Procedure 1.Switch the regulator on. 2.Using VR1001(TE OFFSET) adjust DC voltage of TEY from REFO to 0±25mV.
Adjustment Procedure 1.Load disc and switch regulator on. 2.Position the PU unit in the center of the disc using the TRK UP and TRK DOWN keys. 3.Press key RPT to close focus and press once more to close spindle. 4.Input the L.P.F. output of E to the X axis, and L.P.F. output of F to the Y axis of an oscilloscope by the AC mode, observe lissajous, and check that the grating is within ±45°. (See Waveform 1�3). 5.If the grating is over 45°, make a fine adjustment by slowly turning the screw driver, so that the lissajous is in line. If, however during the adjustment the screw driver should be turned too much and the lessajous should become out of line, proceed to the next grating adjustment 2.
