Kenwood Super 11 has different internals than expected ..

Hey all. Just recently purchased a Kenwood Super 11 and took it to a local place to get serviced. The tech said they did some general maintenance ($299 worth to be exact) and it's in good working order now, but he wasn't able to do everything he wanted to because apparently the Super 11 had completely different internals than any diagram or spec sheet he could find showed him. I've linked a photo in the post of the inside of the unit for anyone that may be familiar with this unit or perhaps any Kenwood experts. I'm sure the tech is correct in that things are different, but I guess I just want to know how/why and maybe what kind of output I'm looking at instead. 

Any thoughts?
