took out the blown components, looks like 4 caps and what I think is a rectifer

-

rest of the components look 'non exploded'

-

might be worth ordering up these parts and some correct fuses. Why is the board covered in that white glue?. is it to keep parts still?, stop ratteling?.....heat dispersion

-

looks bad.........but ill give it a wash and see how it comes up. Looking at the soot on the board it seems that it moved away from these components. There does not appear to be any other visible damage anywhere else

-

any advice is very welcome at this stage
