    Would these old rubys still be good

    I have in front of my an older socket 7 board that I killed by scratching a trace around the CPU socket. It has 11 Rubycon YXG 1000uf 6.3v in 8mm diameter. Harder to find in 8mm, but are they worth pulling considering their age?
    Ludicrous gibs!

    sure I think it's worth the hassle. You never know when you might need them. I would put them it a board but away from the cpu cause that is a high heat area; sorry if I just stated the obvious.

      I was taught to never reuse a cap, but I would decide on each situation.

        I reuse good caps from dead boards. Now I use ESR meter to test them but I haven't seen bad one yet.

          i often pull high quality caps from scrap boards.
          mostly polymers/mlcc
          do it at the same time as heatgunning mosfets and vrm chips.

            If you want a somewhat better measure of comfort, charge each cap to ~6V through a 1K resistor and leave it connected to the P/S for an hour or so. This is what the cap mfrs recommend for caps that have not been used for a year or two.

              That is because the dielectric components of the cap breaks down and to rebuild it you need to give it a voltage. for example a cap that is still good but unused for 10 years i would feed a low voltage and gradualy increase it but i tend to use 2.4K OHM resestors for a nice state of current building. of course you would need a desk PSU w/ variable voltage like my 0-30V 0-10AMP one that i built from instructions on the I-Net.
              Sorry if that sounds weird. i didnt sleep last night so i am extremly tired.

                Rubycon YXG are general purpose caps and should not be used in P3/K7 or newer motherboards.

                  No, it is should be YXA(general purpose), not YXG. You should be made a mistake. YXG can find in many P3 motherbaords. I don't suggest YXG in P4 or above systems.
