Capacitor Replacement Thread: Rev. 1

Once upon a time, I spotted a unifying trend across the specific model forums and asked for information so I could attempt to maintain an information resource in a (corrected for procrastination factor = relatively) timely manner: Capacitor Replacement Thread

Thanks to uniserver, information came pouring in at an incredible rate along with topical discussion regarding components and methods from the rest of the gang.

In the two years (roundoff: minus 2 months) since that call to arms, Caps have become a problem of crisis proportion. Ergo, I'm re-booting the topic here, where I again have unlimited editing capabilities.





Be patient, the compendium is a work in progress ( In retrospect, I've never actually finished much of anything. hmm ) as are all my projects.

Re: Capacitor Replacement Thread: Rev. 1

they pretty much killed every picture i ever posted to the forum... witch really pissed me off.
And they are unwilling to fix it...  so all bullshit aside... Dylan has helped me out big time in reconstructing as much as possible
in the Cap Reference section of MacCaps.com,  Yeah feel free to link to anything you want to.

Re: Capacitor Replacement Thread: Rev. 1

I believe I now host the SE/30 image on mcdermd's server, because PhotoBucket likes to lead direct links to a "page". Correct link is here. (Thanks Dylan)

Here's my notes on the Duo 2300c. The caps on the inverter and driver board are extremely fragile. The Duo 230 has all tantalums inside the display, but is assigned the usual tank farm near the power adapter.

EDIT: fix image sizes
EDIT 2: One of these days I might get around to doing an iMac G4. Word on the street is the caps on the analog board buried up in the beehive eventually cook out and the unit doesn't turn on anymore. There's an assortment on the mobo too. I'd do a proper write up. Might merge it with a thread on fixing the weak neck issue (which was a problem 10 years ago, the difference is now there are no parts and no tools).
EDIT 3: Forgot. The Duo MiniDock has several caps in it. Also the UltraDock 16sce models do too, there are two inside, somewhat large beasts.

As capacitors are becoming an all too common issue for our old machines, I've promoted this topic to a sticky.

Re: Capacitor Replacement Thread: Rev. 1

THX, mate! Hopefully this project will come in handy.

I think I've got everything crosslinked to Uni's pages with the pics, I've tweaked the format a bit and I've got a LOT of machines, especially PowerBooks to fit into my architectural (nightmare roll ) framework.

I'll be adding the PowerBooks, 68k & PPC (NuBus Architecture for now) and begin adding PowerMacs (again NuBus Architecture for the nonce) to the list as well.

Suggestions always welcome  .  .  .  content groveled for shamelessly. tongue

Re: Capacitor Replacement Thread: Rev. 1

and we can say,  Caps alot like market rate. They vary in $$ all the time.
Mouser.com for seems to be pretty much the best place to look for caps.

for instance if you are looking for some 16v 47uf caps.
make the decision as to what you want to install,   Stock / Tantalum / Ceramic etc.

So you would type in " 16v 47uf " in the search.

Most of the time it will automatically take you to the Passive Section. ( caps )
and will ask you to choose a Capacitor Category.   

For instance you could Click on Aluminum Electrolytic.

and then click on SMT.

The next thing you could do is sort by price... (Low to High)

Then you start to scroll down... You are probably not going to want the Cheapest, but even
Mousers Cheapest will be LIGHTYEARS better then the Cheapest on ALIEXPRESS.com
Mouser does not sell trash... or counterfeit caps, So you can rest assured, your not going to buy
garbage from mouser.

I like to go down the list and look at Quantity pricing.
if you know you have a Stack o Mac that needs to be re-capped then you
Should just buy some Quantity. As you see the pricing structure changes.
Pricing seems to be ( lots of the time )  1 - 10 - 100 - 500 - 1000 etc
the Quantity's do change, i have seen.

just keep that in mind,  so if you have a stack o mac to re-cap,
then getting a 100 ( 16v 47uf ) would be a pretty wise choice because
lots of macs have these in them.

Again back to the Cap list, once you sort it L to H.
Check out the brands... Panasonic seems to be a really good brand.
Others are good too.

-------------------------------------------------------------

When it comes to radials.  I like to always Choose 105c caps
No reason to buy an 85c cap these days...   Also I like to always get a
higher voltage cap for PSU's, and in general.

So like a 16v cap installed... I would have no problem installing a 25v or 35v
If its a 10v cap...  Would have no problem installing 16v or 25v caps!

keep in mind if you go TOO big... like a 50v cap where a 10v cap is...
there could be a couple seconds power up DELAY, once you flip the psu on after the recap.
To were before there was no delay what so ever.  Just something to keep an eye on.
So don't to too huge. bigger is better... but don't go too huge on er, might cause some
unexpected results.

Re: Capacitor Replacement Thread: Rev. 1

There's three big axials, two little ones and two 47uf surface mounts. Not much to go bad there.

Does anyone have a IIfx that uses the other electrolytic surface mount pads or are they all mostly solid staters like mine?

Re: Capacitor Replacement Thread: Rev. 1

Cayman Systems GatorBox (not the CS version):

4) 10v 1000uF
4) 25v 1000uF
2) 25v 470uF

All but the last two are radials. The two 470uF caps are axial configuration. All are 105 deg C rated (and should be, there's no fan in the GatorBox). There's also a PRAM battery, 1/2 AA just like you'd find inside a Macintosh SE: the one with the soldered terminals on it. On the AppleTalk interface board, I have reason to believe that there are two metal can axial caps. They are marked (symbol)T100 / KEMET / 100UF / 10V20Z / 9006. CB03 and CB05 silkscreen printing marks.

Hi. I finally got my IIcx today. but it doesnt even starts up.
The caps are failed, will replace with tantals.
The phase cap in the psu faile.
can it cause that, it wont even power on?

Re: Capacitor Replacement Thread: Rev. 1

Did you ever get your Iicx going? On mine, the leakage was bad enough that it ate through some traces.

My IIcx had rotten traces at C11 that prevented startup.

My IIci had rotten traces at C12 that ate traces to UE13 also preventing startup.
