It's been recommended to replace DP3, DP4 diodes which I am ordering.  They look fine except the solder joints look burnt.  What I can't find is DP8.  It's a little diode maybe similar to DP3.  I can't tell because it burned up.  The 1st picture is just my board model.  The 2nd shows DP8 under...

Maybe we can help each other out.  I have the same project ahead of me and I've done the logic board already.  Yes, I believe Y is for filter and these can be rounded up to the nearest capacitance and voltage.  The footprints need to be the same or very close, though.  Also, you can start with...

I had the same sound problem and recapping it solved the sound problem.  Pretty much no matter what it's gonna need to be recapped and it is well worth it!  If you are desperate for sound you can plug in headphones.

That's fine.  You can always meet or exceed the voltage and capacitor ratings.  No problem!  So if it calls for 47uf@25v you could do 100 or 150 at 25 or 50, etc.  Just try to get a picture or dimension of the capacitor when you order it so it looks the same and will install the same.  You can...

Be gentle and controlled but firm with every step of the repair.  Disconnect and remove the logic board.  Remove all the ROM chips and RAM boards.  Look up ROM chip pullers on the net and just make them yourself with a pair of old tweezers to remove the ROM chips. They are stubborn and have...

Well, I tried a bunch of things and I think it is out of my scope of comfort.  I feel like I'm repairing a TV more than a Mac.  I haven't even gotten to the logic board issues and with no power it's really unrewarding.  I retraced some bad circuits.  I resoldered some bad joints. I would love to...

Wow, you guys are brutal.  OK, so I found a big problem and I hope I fixed it.  The board is cracked right at the "high voltage connector?" This is where the neck board was caught smoking Here's just some more pics to make this thread more "useful". So what do you think...

Ha ha uniserver, I think your analog board needs to be recapped. :p   Anyways, I tried to be respectable and figure out where the output transistor is on my own, but I give up.  I found a funny picture on the way though: https://flic.kr/p/4F81tG Also, what's the best way to detach the CRT...

The deflection yoke?  There are 7 pins at the butt end of the CRT past the yoke, attached to these pins is a plastic connector on a PCB.  The smoke was coming from somewhere on that little PCB.  I don't want to turn it on again and wait for more smoke to see exactly where it's coming from.  I...

Any luck getting that corroded board to work? I have the same problem and am hoping to revive my classic. So far all i have done is a cosmetic cleaning. I see corroded diodes on the back of the board and corroded traces on top. Also, will it run with the battery case completely removed if...

Hi everyone I'm digging up my old mac classic with the hopes of reviving it. I know its gonna have lots of problems but i hope it ends up a happy mac story. The first most important i think is on power up i get a screaming sound that i think originates from the analog board, hopefully just the...
