janbeta, Some #Apple #Macintosh #Performa 630 capacitor shenanigans going on in the Beta lab today. Main board got recapped although none of the caps had leaked. The power supply is not so fortunate, found 2 severely leaky smaller caps and some traces beginning to dissolve in the electrolyte. I think I caught it in time though, should totally be salvageable. #RetroComputing #VintageComputing #InTheLabDoingStuff
The removed old SMD electrolytic capacitors in a pile on my workbench.
Closeup of the power supply from the Mac. A pretty standard switch mode power supply by the looks of it. Nicely built with large heat sinks on the components that tend to get warm.
Fluoride of the power supply PCB after some cleaning. The solder mask is missing from some parts around where one of the capacitors has leaked. Some corrosion is visible on the through-hole plating it was connected to.
