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.
Great manual, great price. Has a few of the basic operating instructions that most service manuals leave out. Complete instructions for disassembling board by board, safety precautions, schematics, complete parts list.
