 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.
