This is a very good quality print (scan) of the original SONY service manual. The original from Sony is on very thin paper. Nevertheless it is very clear and sharp and excellent readable. I'm very satisfied to have now this rare document. I've looking for it many years (infrequent). It contains very detailed circuit diagrams, exploded views, part lists, PCB view with good readable connection lines. Very recommended.
Excellent product, very clear print. Detailed circuit and assembly diagrams - this enabled me to repair my CD player with confidence. I highly recommend this site.
Fast access, 100% correct and complete service manual
