G3 AIO analog board/psu cap list

[Torbar]

Hey all,
I picked up a G3 AIO Molar Mac a few weeks ago, has some flyback issues so I'll be replacing the flyback with a new one, but figure while I have it open I would like to recap it too so I don't have to open it again in the forseeable future.

Does anyone have a cap list handy for the analog board and power supply handy? I tried looking around but couldn't find any. If one doesn't exist, I can make one and document it in all the standard places, but that'd involve the machine remaining apart for a while while I wait for the new caps to come in and would like to avoid that if possible.

Thanks,
Tom

Can't help with the caps list I'm afraid, but I feel your pain. I'm doing some work on my PowerBook 3400c and had the same idea to recap it while I was in there. No reference material. So I've got to leave it apart for however long it takes for the mouser order to arrive.

Were you able to find what you were looking for? I've got a cap list for the analog board and CRT neckboard. I didn't have to do the PSU on mine.

Thank you so much @bsteckler !

Did you do the recapping as preventative maintenance, or was it starting to have issues with leaking caps?

It was mostly preventative, although I've heard stories of caps getting damaged and not showing any external signs of it. Mine wasn't really taken care of before I got it, so I wanted to do as much as possible

do you have your 3400c cap list? I am waiting for the 3400c to arrive. also, backlight may be dead. any idea on replacement for that if needed? thanks! Also, looking for how to take plastics off molar Mac...

I’ll do you one better, how about a caps list, AND reference photos!

Keep in mind that the 3400c also shipped with a Samsung display so you may or may not need the LCD caps. Can’t help with the backlight though, sorry.

Cool; thanks! Will see when it gets here this week. Would to crack open this molar mac too.. looks filthy inside. Got logic board out, unfortunately had battery leak

Good news about that is the molar macs will take a beige desktop or tower board AFAIK so it shouldn’t take much to get it running again, as long as the personality card is ok.

I already bought a new board with ram, processor etc and tested working. I think the old board is salvageable. The hard part is all the little diodes that came off when cleaning. I removed a few ic chips, cleaned pads, checked traces and all is good. I sent the board to a friend at caymacvintage who may be able to get all those back on, they are tiny. Will see.
