Just had a power supply for a Sipura SPA-3000 die (bought in 2006).
It's a switched mode PSU. It measured 5V off load, but dropped to
about 2V on load. It has a pair of 680uF 10V 105C caps in parallel
across the output, and both had swelled up and had almost no capacity
left. Replaced with a single 1000uF 10V 105C I happened to have, and
it's working again now. Just need to find some way to reassemble the
case safely (I think it was ultrasonic welded before I popped it
apart, as there's no sign of any solvent glue).

I've got about 6 of these units, so I guess I need to stock up with
some replacement caps...
