Repeat the same process on the other panel.
This side is a bit less interesting. You can see which holds up the main circuit board. You can also see the really large Sprague capacitors (45000uF 45V) likely used as a filter for the rectifier.
Interestingly, these large capacitors are screw terminal caps and are screwed directly to the board. Next to these screws you can see the large non-inductive wire wound resistors.
