Followup: this board was still running happily when it was retired recently. For aynyone else needing it, here is what I used. ...

haha yeah, that fan is pretty loud. And also, that's the [i] inside [/i]of the bag.
Thanks, guys, for all your help! I doubt I'd have attempted this without your advice!Re: DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?

Looks good. Voltages booted up pretty close:
+1.5 = 1.5
+3.3 = 3.39
+5.0 = 5.18
+12.0= 12.09
-12.0 = -12.28
5VSB =5.06
I'll let it run for a while on the test bench - any other burn-in procedures I need to know about?...Leave a comment:

As far as I know, only the KZGs are known problem causers. I only replaced those. Are there issues with the OST caps too?...Leave a comment:

Re: DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?
Bam!
Now to see if it will boot back up. Here's hoping I didn't screw it up!...Leave a comment:

Re: DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?
Actually, I need to retract that last. I was thinking the leads were too big; what happened was I was getting leftover solder in the mounting holes, not letting me get the new caps in. which is being a real PITA, because these caps mount on a huge copper plate (on both sides of the board!) and it's almost impossible to heat it long enough to use my solder sucker.
Yes, well, this is in an HD Radio encoder; it's got a custom, proprietary linux build that expects all...Leave a comment:

So, I picked up the Panasonic polys, just got them...and the leads are 1.2mmm wide - and won't fit the holes. Returning them and will likely go with the HMs - which have 0.6mm leads.Leave a comment:

Are there any likely problems or concerns with mixing poly/non-poly caps on a board? I like the extended life of the polys, but don't wanna cause issues.

Yeah, this is an old machine. as I had noted above, I had already replaced the PSU with a new one a number of months ago...wasn't looking for cap problems at the time, so didn't notice them.
Several people have mentioned going with polymer caps. I dunno much about them - would [URL="http://www.digikey.com/product-detail/en/PCR0J152MCL1GS/493-13718-1-ND/4694550"]something like this[/URL] work?
EDIT: Oh, wait, that's SMD - not the right mounting style.

Re: DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?
Thanks! I was talking with the manufacturer of the unit (who used the dfi-itox board), and they were saying they had a lot of those units come in with this problem. wanted $2000 to replace the MB - apparently the working stock of these is really low!)...Leave a comment:

Re: DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?
Yeah, this one is a BE xpi10 HD Radio exporter - looks like it needed some TLC; I've already replaced a flaky PSU on it. I'm guessing the polys have higher heat tolerance? do you have any recommendations for poly replacements?...Leave a comment:

Re: DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?
Hey, thanks! I wondered about the 470s. All the Chemicons are 6.3V; the 16v ones are all OST.
The HM/HN/HZ don't have the failure issues the KZGs do?...Leave a comment:

DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?
Hey guys,
I've got a G4S600-B ([URL="http://www.dfi-itox.com/pages/products/Mothers/RevControl/g4s600-b.php"]this board[/URL]) that has about 2 dozen UCC KZG caps on it. This is in a digital audio encoder used at a radio station, so it's been on/powered pretty much 24/7 for a number of years. recently it's been getting flaky, so I pulled it apart and noticed that 7 of the 16 1500uF caps on the board are bulged. Did some more research, (signed up for this board!) and find that the KZGs are pretty much despised here.
So I'm looking to recap the motherboard....Last edited by jesscat606; 02-19-2015, 02:45 PM. -
Re: New Members - please post your introductions here
Hey guys, 33yo radio station IT guy here, got a radio encoder machine with a bunch of bulging caps - looking around for a way to identify the caps on it, and ran across this site. Seems like a good place to be known and find info, so here I am.
EDIT: on here less than an hour, and have identified my bad caps as UCC KZGs - which everybody on here apparently knows to be made of fail. this site will help me maintain my mystique as the 'can fix anything' guy!
