I am recapping an sx280 dell mb with a kit listed by badcaps. The list shows 3 1500uf 6.3v 10MM caps but my mb has 3 1500uf 16v 10MM caps. My question is "which ones should I use"? Thanks Humphrey1

Re: capacitors
16v caps are on 12v power rail.
Can't use 6.3v caps on 12v rail.

It's possible a previous recapper used 16v caps on a 5v or 3.3v rail because that's what he had on hand. That doesn't make for an electrical problem [16v is fine on lower voltages too] but the only way to know that's what happened is to see a board with original caps [to see what voltage they are] or to check the voltages on those 16v caps with a meter.
.
If you can post a pic of the board (if no camera then steal a pic from the web) and identify the caps positions then someone familiar with that board (or that has one) can tell you what is installed there.

Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

Hey Everyone,
Long time lurker, but I think this is my first time posting.
Just looking for some assistance on identifying some suitable replacement capacitors for an MSI K7T266 Pro (Ver. 1.0). I just got my hands on two of them actually, both working but one has some visibly bulging capacitors and the other has a few that I can't tell for sure if they're bulging because it's faint at best if they are.
I'll be honest I don't fully understand much on capacitor spec sheets beyond voltage and capacitance but I can solder like nobodies business so I've... -
Howdy folks,
I have an Optiplex GX260 that blew a couple of those troublesome Nichicon HM series (ultra low ESR) electrolytic capacitors. Because said caps are obsolete, they are pretty much impossible to find on the market; I did find a listing for some but I believe they are counterfeit. I feel the easiest thing to do would be to replace all the blown caps with polymer ones. I am by no means an expert in electronics, and I've found a fair bit of conflicting information, so any guidance or confirmation would be greatly appreciated. While from a practical standpoint it's not worth... -
Hello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and... -
I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...
