iMac G3 - Capacitior List?

[maceffects]

I have a 700mhz iMac G3 that I'm looking to see if a capacitor list exists so that I can order and match capacitors.  Can any direct me to where such a list might exist? 

 

[maceffects]

I should mention I’m looking for the analog board capacitors.

I would also be interested in such a capacitor list, I am working on an identical broken 700MHz iMac, however on my machine the logic board is broken, not the analog board.

Here is the capacitor list I made for my iMac G3s. They are iMac DV SE (Special Edition) 400 MHz "Graphite" models. While obviously not quite the same, perhaps it can be of some use.

Do you think this list would work for the non-dv first gen blueberry slot load model (same except for the 350MHz FireWire-less video out-less board). Mine unfortunately is in need of a recap (ugh) so I should probably get on that soon...

My guess is it would be similar, particulalrly for the analogue board, which I would imagine is unlikely to have changed significantly between the 350 and the 400. The only way to know for sure though would be to cross-check your board against the list, but this at least would give you something to start with.

Out of interest what caps need the most attention on the iMac - PAV, or analogue board? I've an iMac G3 233Mhz that displays power issues, all caps look OK - there are many ....

Mine boots fine but the CRT geometry has problems. It is clearly a very high hour tube (the hard drive had some 28 thousand hours on it among other things), but the problem is that whenever I open a window (or whenever anything changes), the image shifts. My guess is that the caps have just been expended up their usable life, not some time related failure.

Welp, I used this list for my 400mhz Indigo DV. Here's the notes I have:

Some of the 16v caps in the list are 25v on my board. All 16v caps in the list can be replaced with 25v to mitigate this issue, there's plenty of space.


Analog board:
C905 is 560uf instead of the 470 that the list has.
C723 is actually 220uf 160v, list has 33uf 250v
C931 on list is actually C938 on board (470uf 16v) [they are right next to eachother, but 931 is a film or ceramic or something cap, but it's obscuring the 938 designator from some angles]

logic board - disregard all caps in list. C178, 2301, 2302, 2501: 47uf 16v (space constrained, don’t upsize)C130, 1740: 220uf 10v


I'm necrobumping this post in particular since it's the first google result for "imac G3 cap list"

Here's a digikey list I made that DOES NOT INCLUDE THE CHANGES FROM MY NOTES ABOVE
https://www.digikey.com/en/mylists/list/ZTT159RSQ2

I didn't replace any of the caps on my logic board but the rest I was able to substitute with caps on hand, or in the case of C905 I just left the original in since it tested perfectly. The recap was a success!

Congrats! Glad it could be of use, even if there were differences between the two (and one error, thanks for pointing that out!)

Thanks! No worries! Thanks for making the list. Saved me a *ton* of time and effort.

Anyone else who finds this thread, please note that the digikey list I linked above does have the capacitors annotated both by designator and which board they go on, but still doesn't include the changes from my notes above.
