Then there is Chemicon, they have this empty rectangle logo.

I still run 2 SUN systems at work, one made in 1998 and one made in 2001. Those have been running mostly 24/7 and so far show no indication of stopping. OK, had to replace a dead HD now and then... That means, you CAN build systems that use electrolytic caps that last a long time. It's mostly a matter of paying a bit more for the caps and using more of them than the bare minimum (*) (*) On some boards you see empty spaces for caps. The designer thought they were needed, then controlling came and removed as many caps as possible to save some money... If I repair such a board, I don't just replace the bad caps, I also populate the empty spaces. Gerrit Message was sent through the cbm-hackers mailing listReceived on 2017-02-26 15:00:02
