Interesting video on recapping capacitors in a Macintosh 20SC Hard Disk power supply here. Also useful for learning some general electronics techniques, and it was good that voltmeter and oscilloscope readings were used throughout.

The result? Well, yeah, the result did work okay, but I was not impressed with the performance compared to the original. Yeah, “if it ain’t broke, don’t fix it” is still the side that I am on… though apparently there were already some leaky capacitors. But, what makes me feel bummed about this. Dang, that Sony engineering, they really know how to build with craftsmanship, absolutely no corner cutting on the quality whatsoever. They put all their cards down to make the product of their work as maintainable as possible for whatever future generations may come to. No wonder why Macintosh computers hardly had any malfunctioning problems back in the day, while PCs were wrought with hardware AND software problems that would cause random freezing, crashing, and rebooting.
