Okay, getting into the recapping. This is using a preassembled kit. You can buy them for many vintage electronic devices, because we haven't figured out how to make ones that don't fail yet. So they fail, constantly.
The kit comes with a sheet saying which caps are what. Some nice ones label the caps themselves, or stick them in tape with labels on it. This one just has a printout with the values and positions, and you have to figure out where they go.
Rule of electronics repair #2: Go slow. Slow and works when you're done beats fast and broken every time.
