    Replacing tantulum capacitors with electrolitic caps?

    Just like the title says can i do it? Im replacing tantulums on ps3 consoles, and im all out of them , but i do have lots of electrolitic ones... Its the supply rail of CPU and RSX video chip , some people say they create alot of noise and maybe they could be used in combination with tantulums and it should work fine? Any thoughts?

      tantalums or surface-mount polymers only.

      what are you actually replacing?
      the only things that need replacing in ps3's are the tokin caps - those are ceramic, not tantalum.

          Ye those tokin caps... I have run a wire outside the metal shield and connected up some electrolitics . and it works fine. Im not sure how long these would last... but eh
          Hmm i always thought they were tantulums... interesting...

              those wires will have a high inductance

                  What is printed on the body of the cap?
                  And yes, a piece of wire is seen as inductor in high frequency circuit.

                      And if the Tokin ceramic caps are surface mount MLCCs their ESL is very low.

                          TAGAN TG380-U01 PSU - 5v shorted after replacing caps
                          by kotel studios
                          Hi

                          Recently I got this tagan tg380-u01 PSU with bad caps on 3.3v rail (the line was 2.5v no load!). Replaced them but no go, so I've replaced all of them, apart from some smaller ones and one under the secondary heatsink. Even that didn't help so I've replaced the others. All caps are known good ones.

                          Powered it on and heard the breaker pop. Opened it up and saw some smaller caps shorted together. Fixed that up but still it trips breakers. Now I get 0ohms from 5v to GND. Secondary heatsink removed and still a short, even with the PWM IC board removed. All diodes on that...

                          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...

                          Replacing caps in an old speaker system. Should I use a higher value here?
                          by Delicieuxz
                          I'm recapping an old Creative Labs / Cambridge speaker system / subwoofer. At 4:33 in this video, the person looking at what he says are the speaker caps in the system says they are 470 uF, and that he'd use much larger caps if he was building it.

                          https://youtu.be/1LRIzePlma0?t=273

                          I'm wondering if I should use something larger for the recap job, and what using larger caps will do for it.

                          Would 680uF be good value to try in place of the 470uF originals?

                          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...

                          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...
