Macintosh LC Cap Question

[360alaska]

Recently, I Purchased a Macintosh LC in pretty good shape and working but of course needing a recap. I'm just curious if anyone knows why my board has a large thru-hole electrolytic instead of a surface mount? Maybe it was some sort of modification to support an accelerator or something?

That looks like it was re-capped before. Probably just that one. Closer inspection of the solder on each side will tell. Could it be factory? Maybe. I seem to recall a case similar to this.

That looks like a repair done a long time ago. It looks good from this end so leave it. Replace those little tin cans "South" of it.

Q: Does it turn on and boot properly?

After the logic board, recap the PSU Next.

Yeah,

I've had him for 2 weeks, I recapped him and replaced said capacitor with a 3300 16v:



It boots up to system 6.0.8 which I was using until I found out that "The Yukon Trail"  will only run on System 7.1 so he's running 7.1:



I also spent 70 dollars on him and replaced the working 40 meg scsi with a scsi2sd and I had a spare IIe card and even though I'll likely never use it I put that in there too. It had 10mb of ram and I swapped in a 512k vram stick! Now I just need to find a silent fan replacement and a nice LC topper CRT

As for the capacitor I'm still pretty curious as to why somebody would replace it with a hug electrolytic but who knows.

I found another like this online:



Maybe this was an apple repair after a factory reject?

it was factory... i have seen many many LC's with that big honker on there.  Thinking it was compensation for something that was not quite right in the REV1 production boards.
