            btw, mac g5's do that too (hence the poly kit). too hot to handle.
            Uhh, don't talk shit about stuff you don't know?
            The Precision 470 is not some kids system, it is a workstation system
            It has excellent cooling, hell, if you want to populate all RAM slots it will even force you to buy an extra fan for that!
            This system with failed Rubycon capacitors has some issue, either broken fans, broken PSU or non genuine Rubycon capacitors, it would never be able to cook genuine Rubycon capacitors if working properly

              Just in; Silicon Chip September 2010: bad JFD units in an 18-month old HD set-top box. It was on top of a DVD player in an enclosed entertainment cabinet.

                  Re: List of Bad Cap Manufacturers

                  are XICON caps any good? blue with black lettering. thats what most of the ones at the local electronics store has. i recapped a cheapo powmax 450w with them (only 2 in that psu were bulged so i replaced them and the one other of the same specs) and it seems ok...

                    XICON are not low ESR.
                    If you put that PSU on a scope you'd be scared.

                        I was investigating a problem with my washing machine today.

                        The PCB has 4 Capxon on it, whoopee!

                        Seems to be happily running through its wash cycle at the moment (thank goodness). I may replace the Capxon later.

                              Almost all caps on the controller board and the 1000µ PSU cap.

                                I have done a recap of my Marantz CD10, I found 4 Rubycon Black Gates in there which were leaking....
                                They were 15 years old
                                Are they crap or not?
                                Anyway I put Pan fc in there
                                What about Multicomp?
                                I read in a post here that they are not low ESR...
                                But are they crap or not?
                                I may want to put 2 100uF / 6.3V bipolar in a protection circuit of an amp
                                Usually there's no voltage on them only when the protection starts working

                                  Multicomp = multiple companies = generic.

                                  Bipolar are used when the polarity changes in operation.
                                  A low ESR bipolar would be rare if any even exist.
                                  Both sides of the aluminum foil have an oxide layer [dielectric].
                                  Using them in a circuit that doesn't reverse polarity will eventually erode [remove] one of the oxide layers effectively turning it into a polarized cap.

                                    Ok
                                    But there has to be a reason for choosing this type of bipolar cap
                                    It's the protection of an Accuphase power amp
                                    Knowing Accuphase....
                                    For now I put in 2 Pan fc's
                                    Not entirely good but it'll work until I find good bipolars
                                    The old ones were Elna... 20years old or so and leaking
                                    But it won't be Multicomp
                                    I saw a few Nichicons at Mouser
                                    I just hope they're the same quality like Pan fc

                                        In an old TV set (late 80s) was a bad DIACON bipolar electrolytic used for coupling of the horizontal yoke.
                                        Ever heard about this brand of capacitor?
                                        My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.
