Macintosh Classic I Analog Board replacement capacitor list

[Will Cheyney]

Hi folks.

Can anyone point me in the direction of an exhaustive list of the the capacitors found on a Macintosh Classic I analog board?

I’m surprised I haven’t been able to find a resource anywhere online that lists all capacitors found within the compact Mac’s... unless there is and I just haven’t found it!

Many thanks.

If you don't mind old-school, I have a notebook page with them all I can take a pic of and post.

Yes please - sounds ideal!  
Thank you.

Here they are. When I take apart a machine I haven't done before, I make one of these .

While it does not have entries for every possible vintage Mac, I have found the capacitor lists here to be incredibly useful when there is a page coinciding with a machine I am working on.

Good luck with your Analog Board!

I have two excel files. May be helpful.

I learned the hard way with @ArmorAlley when we tried to recap LC PSUs that you can't 100% trust PSU cap lists (Turns out there can be major variations within the same brand/model). For the Classic alone, there are two board revisions which may have different caps. If you take into account the differences between the 120/240V versions, that makes 4 possible capacitor lists... (they may be identical, I don't remember TBH).

For those reasons, I just prefer to open up the unit myself and make a list per actual machine. That way I can also get their sizes and buy the highest rated one (hour wise) or the one with the lowest ESR value within the original's size specification. Also, one last recommendation, Nichicons are probably the best caps out there. 

Just my 2 cents though...

Keep in mind that some diodes are also worth replacing, two of them are bad almost every time. (DP3 and DP4)

Eagle, your point is well taken, especially with PSUs. I always check what I have taken out with what I ordered. You never know. I’ve found different things as well.

Hello this thread was very helpful but did not tell me exactly which caps are best to replace , you really only have to do 10 . Go to Brachus Creations above for that info . I was working on my Mac Classic 2 but I am assured this is also true for the Classic Mac Power board (analog board ) But attached the caps removed with values and sizes to make ordering easier . All sizes in millimetres .
