I recently picked up an Performa 410 (LCII education model) and have started down the road of recapping. The motherboard is mostly under control, but I'm having trouble figuring out what's up with the power supply.
Unlike most of the guides and videos I'm seeing online which are based around the seemingly more common TDK or ASTEC power supplies, my machine arrived with a "Dyna Comp model DCF 353" (Apple part number 614-0028).
Before disassembly, I checked the PSU with my multimeter and got some wonky readings. +12V was OK... +5V was closer to +2.5V and erratic... and -5V was really really low and erratic.
I went ahead and desoldered all the caps, and then tested each one with my multimeter. Seemingly they all can make it up to infinity.... so I don't know if they're really bad or not.
So I guess what I'm asking is:
* Does anyone here have any words of wisdom in dealing with this power supply?
* Does anyone have a saved Digikey/Mouser/Arrow parts list that I could use for the replacement caps they'd be willing to share?
Thank you!
