    Recapping ATI FireGL V3350

    I've just got a used V3350. There r 3 Rubycon ZA 10v 470uF 8mms on the PCB. Eventhough ZA is not bad, I decied to recap it.



    At first, I wanted to replace the ZAs with Nichicon LFs or FPCAP R7s, but I founded that they do not provide 10v 470uf in 8mm diameter.

    Then I found some pics of this card on the ATI website, also found that they use OS-CON SVPC 2.5v 1500uF 8mms for the offical version.



    Do U think it's going to be a problem if I replace the ZAs with lower voltage poly caps?

    Seeing as how they seem to interchange them, I'd say probably. But, you should measure the voltage across the caps while the card is running just to be sure.

      What's the suitable voltage?
      4 example, I measured the volt. is 10v, what kind of cap should I use?

        i say: real-volts * 1.5 = minimum cap.

        so if it's 10v then a 15v cap - ofcourse there is no 15v cap so you would use 16v

          He means measure the voltage across the caps with a multimeter when the card is running to check the actual voltage going through the caps, the 10v rating on the cap itself is just a maximum voltage it can take.

            I understand what he means, but just one question: Should I measure the voltage directly on the PCB or remove the cap first?

              Directly on the PCB.

                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).

                https://www.badcaps.net/filedata/fetch?id=3591772

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

                Recapping Sony ICF-SW55 - verifying cap values
                by proxneo
                Dear reader

                I am performing a repair on a Sony ICF-SW55, which includes recapping (some) of the SMD capacitors on the mainboard. I am looking for verification of their values. At the moment, I'm 95% sure I've got the right values, but it is hard to find some official, credible or multiple independant sources on this.

                At the moment, I have selected replacements based on the following list of values:

                3 x 470uF 10VDC
                3 x 4.7uF 35VDC
                4 x 47uF 50VDC
                8 x 22uF 6.3 VDC
                1 x 220uF 6.3VDC
                5 x 100uF 6.3VDC

                Which...

                Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
                by flibidy
                I have here a Magnum IA.100 which belongs to my parents.



                The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


                Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.


                What Ive done........

                Help with replacing Capacitors on Altec Lansing ATP 3
                by yuzupatogik
                Hello,
                I have this old (2004?) Altec Lansing ATP3 and i would like to replace the capacitors. I have identified 34 out of the 36 of them as Samxon GR of various capacities and voltages.

                I can't find datasheets for the Samxon in any of the following variants:

                10000uF 25 v - this one i really want to replace because i suspect it is what causes a dull hum regardless of the volume knob position or if the source is plugged in. I am eyeballing the Rubycon 25PK10000MEFCGC18X35.5 for this purpose. So if i pay a 10x the price part for shipping i might as well go ahead and...

                Recapping KRK VXT6 without original datasheets
                by slerner
                I'm desperate to save my pair of 2007 KRK VXT6 studio monitors, one of which died.
                Hoping for an easy fix, I bought a pair of new-old-stock replacement main boards. I installed one & it was DOA. Tried the other, also DOA. I suspect that 15 years in a Maltese warehouse dried out the electrolytic caps. I tried replacing just the two largest caps, which didn't help. Except to confirm that the old ones wouldn't reach infinite resistance & were a gram underweight.
                Q: How do I match the caps, since there's no series marked on the originals and no circa-2007 catalog or datasheets...
