So far this power supply is a nightmare. The person who hacked this power supply has done 2 things wrong. 1. used a soldering iron that is way to hot for the job. and 2. has used crappy solder. By re soldering a lot of the pads they have done more bad than good. The reason that there are jumper wires all over the place is because the solder through pads have been damaged from over heating. I.E if you put one multi meter probe on a pad on the bottom of the pcb and the other probe on the adjacent pad on the top there is no continuity. It will not be a quick rebuild but it is repairable.
