    One thing comes to mind: WTF?
    He says that sound quality improved after removing the sleeve.
    I wonder how much electrolyte the wood or the rice paper would absorb and how much was lost while the can was removed.

      Isn't the can _part_ of the capacitor that is in a constant cycle of oxidization and solidification?

        sounds like snake oil to me... a placebo at best.

          When capacitors dry up they fail.
          I'll let you conclude by yourself the difference in absorption in aluminum vs ricepaper & wood

            I can't remember where this one picture came from, Could even have been here.

            I guess that'd be a capacitor mod for sure.

              Someone needs to try it and measure the results.

                At the center of the audiophool nutjob ring is this guy! Stuff like this is why they've earned the nickname.

                Nothing prevents electrolyte from evaporating like wood a porous substance!

                The electrolyte is either going to evaporate through gaps in the top and bottom seals or get absorbed into the surrounding wood and evaporate through the pores. Then the ESRs going to go through the roof and the caps will be trash.

                It seems like the more they believe in this stuff the less they know about the components they're messing with and electronics in general.

                  Expensive audio grade caps weren't good enough.
                  Does he even know why caps are encased in aluminum instead of rice paper and wood?
                  Of course, these s have deep pockets, so when the caps dry out they can just buy new ones and perform the same mods to them.

                    K people like this are on crack. There's no way you could possibly tell the difference by taking off a plastic sleeve? O.o

                        Now if he had used glass instead of wood it would be a different story.

                          I wonder if the changes he's hearing are also the result of the electrolyte drying up...

                                      Or they heat up and blow out the bung or release vent. Here the cases are lacquered shut, so they will be able to reach significantly higher pressures before something gives. The only thing that might prevent these firecrackers from exploding is a failure of the seal around one of the leads, relieving the pressure before the whole thing goes off.

                                          Capacitor detached from PCB – RTX 2070 Super Founders Edition

                                          Description:
                                          During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
                                          I did not notice it detaching, so I am unsure of its original location on the PCB.

                                          Procedure performed:
                                          - Removed backplate
                                          - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
                                          - Reapplied thermal compound
                                          - Reassembled card

                                          Observed behavior after reassembly:
                                          - GPU powers on and operates normally under...

                                          Hi people, I hope this is the correct spot to post this, I'm new to the forum.

                                          I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

                                          I hope these photos make it clear which component I am referring to:
                                          (yes, the soldering is a bit botched from removing the blown one, I know)

                                          I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

                                          Dick Smith Q-1760 linear power supply filter capacitor question
                                          by Agent24
                                          I have acquired a used Dick Smith Q-1760 power supply - although the OEM is Manson Industrial
                                          It has at least one problem.

                                          The voltage control potentiometer VR2, 50K is faulty - going high resistance / open circuit in the CCW end and leading to the output voltage jumping around.
                                          I have already ordered a replacement potentiometer, so that's not an issue.

                                          Now, I want to replace all three electrolytics on the PCB as they are CapXon and I don't trust them so much, I will replace them with something better while I've got the thing apart anyway.
                                          All are CapXon...

                                          I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
                                          Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
                                          It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
                                          So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
                                          I know that these capacitor will not last as long as nichicon capacitor...

                                          How can I test non-polarized capacitor?
                                          by chth96
                                          I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
                                          I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

                                          And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
                                          I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...
