    (crossposted to and

    I was looking through electrolytic capacitors for yet another
    bloated-capacitor replacement for PC SMPS repair when I decided to
    take a gander at the manufacturer's data (looking for the longest
    rated life at the highest temperature so with luck the new ones will
    last a few years), as pointed out by Digikey:

    I saw some interesting-looking titles in the lower-right under
    "Aluminum Electrolytic Capacitor Data Files", specifically the
    "TECHNICAL GUIDE." Clicking that goes to another webpage with PDF

    Most notable is Section 7, in the file at tle link below. It all looks
    reasonable and objective until it gets to Section 7.2 on audio, which
    starts on the third page of the PDF file.

    (here's the payload, folks):

    There are only two pages on audio, but it has the highest density of
    undefined/undefinable words I've ever seen in a "real" technical
    document. I've never heard of "amount of deta" but I'll guess that
    deta is short for detail.

    only if they are free range caps tho'.... and not grain fed

    They're not as useful as organic transistors.

    You can buy them at Hole Foods.

    Total crap, appealing to the dumbness of today's users and designers.

    There ARE some aspects of construction that will affect electrolytic cap performance,
    notably microphonics ( got hit badly once by purchasing's decisions once on that aspect
    ) but this smells of nothing but marketing bullshit.

    I think you mean 1000%.

    Probably a post from the fake 'soundhaspriority'. Did you lose your account with
    Buzzard, diddums ?

    LMAO ! And 'real ale' will enhance the effect even more. ;~)

    At the expense of greater leakage.
