    A temperature controlled Weller or Metcal with a reasonably high mass tip would probably do OK. Not that Weller is cheap or Metcal is in any sense inexpensive.

      I am not exactly sure what is reasonably high mass tip, but I use 2.5mm^2 solid copper wire for my 150VA gun.

        I don't think its vrm out, so I would not risk 2.5v.

        the 3.0 version of the board had the cap as a real polymer there, I think its a reg cap for that chip up there

        the output vrm is lytics

          The image in that URL shows wet electrolytics, not polymers. Those are sleeveless Panasonic FL without a vent stamp. Behemot dissected some 6+ years ago.

          The font on the failed 680uF 4V capacitors reminds me of Suncon (formerly Sanyo's electrolytic division). The font and vent stamp are both a match.

            Seems like these custom short caps were quite common for a time of the 775 era. Always around the socket, under heatsink.
