Hi! Im repairing a burned pcb from a musicson p-802
I have the scheeme and another working module.
As the damage is soo deep....im thinking in cut the burned part of pcb and do another with my new laser engraver
If its posible....someone have the pcb layout of this amp? Or think is better refill holes with epoxi and try to make conexions again?
Pd: burned by a broken electric generator, around 300 volts 🙁
Pd2: i tested isolation with polimeter in 2mohms and dont have continuity between burned areas

No ! Make another board. I'm sure many components are fried & carbon is conductive.
