Hello everyone this is my first post (after my intro post) so forgive me if i'm a bit nervous asking questions, or making a long post i just like to explain myself as best as i can..well i have a Apple Emac from 2002-2004 i got it from my old highschool before 2009 (they were going to get rid of them...recycle them etc..) so i managed to get one and it sat in my closet for a while and got used sparingly just for web browsing etc, but a couple of months ago it was working fine until i noticed it started shutting off at random, and a odd noise was coming from the speakers, i've never opened it except to remove dust, after disassembling it completely i noticed the step down board, with capacitors with a brown/reddish covering so i thought they were chemicon's except the weren't...i thought they were i removed the board almost every single Sus'con capacitor was blown with the exception of one tiny one.the rest were spilling electrolyte everywhere..i thought the damage was confined to there, after removing the logic board every chemicon capacitor had blown, and nichicons as well, the only ones that didn't blow up were the black matsushita ones which had me confused....anyway i recapped the stepdown board however i am puzzled with some of the caps, i think i did a acceptable job replacing them these are what i used
Nichicon PW 35volts 1200uF 105c
united chemicon EKY 35volts 680uF
Nichicon PW 10volts 1200uF
panasonic m 1000uF 16V
panasonic fr 16VDC 1500uF
my question is are these good choices, does a step down board need low esr caps? only one cap is 85C else is 105C i attached pics to show what i did those suscon caps were huge as compared to these which are much much smaller...i left a suscon cap there till i got a replacement for it a rubycon light blue cap from radio shack i dont think its a bad cap but i could use some advice....the only other cap i had was a lelon cap which is crap...what are those light blue caps? fakes?( radioshack which is closing down so i got a lot of rubycons) thanks for any help you can provide
