Replacing the potmeters on the 300 W, 20 A DC-DC converter

I had to do some repair on my DIY power supply and I had to replace the buck converter in it. I thought it might be useful for some people to see how the voltage and current adjusting potmeters (CV and CC, respectively) are wired up and how they can be replaced. It is not a complicated task, and I recommend doing it if you want to change the output often. It is not too nice to adjust the live circuit by a tiny screw very close to the connections.
