Here are a few photos of mine. As you can see, everything is pretty compact.
There are several separate PCBs. There are several pages of schematics. It would take me a good bit of time to try to figure out just what is what.




As you can see in this photo, there is a surface-mount PCB with some pretty small components, which would be a challenge to desolder and replace.




The manufacturer of the speakers says they can not or will not repair them, plus they are in Europe. Highly skilled electronics people here in the United States could most likely repair these units because I don't see anything that would be hard to get in parts. Perhaps some of the operational amps would need to be replaced with newer components, but the specifications would most likely work.

Let's hope none of us have any failures. There is a limit to what is logical to repair in any event. The A7 schematics I saw on the DIY website were dated 2006. I have had these for about that long.
