    Two Leadtek Winfast A250's found with bad caps

    A friend and I ordered identical hardware back in 2003. I recently posted about our Soltek mobo bad caps. It turns out both of our video cards have bad caps as well. These are Leadtek Winfast A250's with a Ti4200 and 128 Megs of memory. My card is still working, but my friend's card has recently developed strange problems in the 3d modes.

    On my card:
    GSC 330uF 6.3V - isn't bulged but has leaked
    GSC 1000 uF 6.3V - is beginning to bulge

    On his card:
    GSC 1000 uF 6.3V - has bulged and leaked.

    He sent an e-mail to Leadtek, and they responded immediately, offering him an RMA to send in and fix it. He has sent his card in, but I'm holding off for now. I'll be curious to see what brand caps they choose to replace these with.

      Probably the same thing that was on there in the first place...They'll probably bin the old card and grab a similar one and send it back to your buddy.

          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."
          ...

          Help with switching power supply caps
          by captain150
          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,...

          Gigabyte GA-6OXT :: caps question
          by Foetuss
          Good evening

          I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
          Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

          But I was also suprised about the bigger boys, which are 330µF 25V.
          Could it be they used 25V caps because they were cheaper / available at that time?...

          EVGA e-GeForce 7600 GS AGP 256MD2 [256-A8-N542-T2] with bad caps - fixed
          by momaka
          I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)

          So, here is the...

          Replacement caps for Samson Resolv studio monitor 65A Amp board.
          by black6host
          Good day!

          I have a Samson Resolv studio monitor that has no sound output. I've opened it up and found two caps that are bulging on what I believe to be the power supply section of the amplifier board. The board is marked Resolv 65A AMP V1.2. The caps in question are YUSCON, 2200uF, 35V, 85C temp and have markings of RA(P) and are 16mm x 25.5mm tall. I've attached the schematic and the caps in question are C5 and C6. I'm assuming they are low esr caps. I've tested both caps and they test low uF, nowhere near 2200uF.

          I'm going to replace the caps and I'll be the first...
