Good qulity. Even as it is an old manual (from 1991-1992) it has a good scanned quality and is complete, including user's manual, disassembly intructions, diagrams and schematics, ajustments, troubleshooting and parts list, as usual with SONY manuals and Owner-manuals service.
Quality scan, great manual. I solved my problem with this manual.
