Yup, that's a duff electrolytic all right. I recently replaced 15
like that one in a PC motherboard. The lowest was at 300 OHMS!
The hardest part is getting the solder out of the holes when there's
a nice solid ground plane to take all the heat away from the iron.

I got new capacitors from Farnell, about 50p each.
