 771 SANSUI Service Manual by Laurence Pike;
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.

 R30 SANSUI Service Manual by Giovanni Bianchi;
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. Giovanni Bianchi
