    Sorry if I wasn't clear.  I did two sets of cap replacements: the first
    was replacing the 1000uF/10v caps in EC{18..25} with identically rated,
    non-Jackcon caps; the second was replacing the single 100uF/10v cap in
    EC10 with a 1500uF/6.3v one.  The first I did because one of my originals
    popped and the rest were looking suspiciously like problematic caps in
    my VP6.  The second I did as recommended in several places, one of which
    quotes Abit UK thusly: "...all that is required is to replace the EC10
    capacitor with one, value 1500uF/6.3v."  So, yes, EC10 is replaced with
    a 6.3v, but it's the recommended fix and the original cap is the wrong
    one anyway.
