Great value, good scan, just as expected, everything that you need.

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.

* If a trouble is detected upon turning on the power, CPU turns off the speaker relay. And if the trouble is not recovered within 2 seconds, CPU turns the unit into stand-by. If DC offset or over current is detected while the power is on, CPU turns off the speaker relay. If overheat or some trouble is detected on the main transformer, CPU turns the unit into stand-by immediately.
