What do those resistors pertain to? And actually to clarify I didn't mean the capacitors 'blew'. But I think they are bad.

Well without the power board it won't do Anything. At least my 3 would not. Any corrosion below the battery and all I can say is good luck.

I have a 3400c that had some corrosion beneath the PRAM battery.  It wasn't actually that bad, and I've cleaned the board with still unknown results.  Hopefully three capacitors on…

I am having the same exact issues with my apple 3 almost to the T. If you have solved this issue please let me know what you tried. I noticed my power supply is making some weird n…

usually the main filter cap is always good, just replace the brown leaky ELNA ones. the only problem you may find during the process is a corroded circuit board, just spend more t…

" i don't have any brittle plastic issues with any of my power book 140 - 5xx " Ohhh don't worry,  its inevitable.  

Someone should start a business making and selling new replacement parts for old machines (like cases and fly back transformers). Someone is already making the floppy drive gears, …

One more: what's the line filter capacitor voltage? It just says 47uF, I don't see a voltage. I am guessing it's 250V?

You can get a 20a max multimeter at harbor freight for a couple bucks, Mallet works good with portable battery packs as well !

More questions, and my $.02: My multimeter has a milliamps up to 200mA, so I might have to go get an extra analog one, plus it won't even give me mA reading on a battery. My multi…

Maybe you can regulate them down to 1.5 amps and sell em to portable users, There is a market for such too!! I'd buy one from you. Portable users need 1.5 amps. 1500ma …

Just a question, if they are dead, or "suspicious", I am guessing it is capacitors? What else could it be, they're power adapters.

Good luck with it! You will get them working again!
