What is your experience in this matter?
Are you aware that WANG'S CAPs is a pure poo 3rd grade Taiwanese brand of capacitors ? I don't even know for a start why Atari installed such junk inside their computers instead of using Rubycon, shoei or panasonic capacitors.
check the site called Bad capacitors, they have listed the poo capacitors companies, and guess what, Wang's caps are in !
Those have to be removed and replaced, since they had a lower life span than 1st quality grade capacitors like the ones i cited above.
Just to illustrate, in my ST machines, once i recapped them (removed the Wang's caps junk caps), by panasonic and nichicon, which are doing a way better job than their old counterparts, the display was then way clearer and brighter than before, and the noticeable dim i got on screen each time the ST accessed the floppy drive disappeared.
Atari only used good quality caps on some ST series, but not all unfortunately, this to cut their cost.
