    Need help understanding Caps

    I have successfully replaced the caps now on two motherboards - using exact same caps but new. Now, I think I've got the hang of it. I have three more mobos that have cap issues - all older dell machines. The caps that I keep seeing needing replaced are 6.3v 2200uf. Looking at Rubycon stats, the 6.3v 2200uf has a ripple value of 2770 and ESR rating of 11. I've heard you can go up in voltage and it should be ok. Is that right? If I increase to 10v 2200uf Rubycon with 3230 ripple value and ESR rating of 9, should the caps last longer than going with the 6.3v exact replacement?

    There is a slight larger height but I have plenty of clearance. Do I understand correctly that you want larger ripple and smaller ESR and voltage doesn't matter as much as long as you replace with higher value?

          Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
          by momaka
          I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

          For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

          It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

          Heathkit IO-4205 Power Supply Caps
          by eryjus
          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."

          Dell Optiplex GX260 - Advice Needed for Polymodding Motherboard
          by SwedishDiesel
          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...

          Identifying caps on an old Zoom 9000
          by Paxman_Swede
          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...

          HannStar Hanns-G HC194d LCD monitor repair
          by momaka
          Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
