Thank you all for your suggestions. This model is a bit strange. I think it has the power supply split into two modules. I believe the one PCB in the metal shielding is the primary supply and the other PCB next to it is the secondary one. And I noticed it's a 110-240V machine with no selectable voltage. Does this mean it uses a switching power supply? And what are these pots that I have circled? My VTC 9350's power board has a pot for 12V adjustement. So is this case the same here?
