 UC-K3 AKAI Service Manual by James Dunham II;
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.
 AA-V435 AKAI Service Manual by James Dunham II;
This service manual includes drawings, schematics, exploded views, parts list, operating details, and more. Very good scans, very readable. The only thing that made it a 4 star rating was on approximately 4 scans only half of the page was scanned then the other half. I would have preferred the pages to be whole scans.
