Next up are a couple of SP15 repairs ......

The dual MOSFET chip has melted and released it's quota of smoke and vapours ....


Sometimes, the evidence for the chips failure is not always quite so easy ...

The larger arrow shows a degree of discolouration on the solder pad of a diode. A further clue to the problem is highlighted

excessive heat ....... note: the wires for the braid pickups have been removed for clarity.
