Good scan, great price, but almost the same with the SV260 service manual.

This PDF is very comprehensive. It includes drawings, parts lists, schematics, pictures, PCB drawings, mechanical layouts, etc. for all three stackable equipment. The scans are good too. Easy to read and no smudges or black lines. I have no complaints. I will make this site my first stop for finding my service manuals.
