I'm considering redoing the capacitors on my Mac IIci and Mac II boards which stubbornly refuse to boot regardless of what I do them.
I've looked at both boards and noted the locations and sizes of each of the capacitors that will need replacing.
What replacement for the 3 x 470uf and 1 x 200uf axial aluminium capacitors do you use? I presume the only option with these is to replace them with 'like for like', but what ESR and Ripple Current specifications do you select? I again assume the lowest ESR you can ideally get but are there optimums you shouldn't go above or below?
The 47uf and 10uf I assume are replaced with Surface Mounted polymer or tantalums? But again what ESR and Ripple Current specs do you look for? As I understand it (and I'm a newbie to electronic components) for motherboards the ideal is a low ESR and high Ripple Current, but what specification is considered low and high?
Cheers!
