Thanks so much for posting that cached link. I knew I'd seen something
about the capacitors before. First Logitech kill the Slim product line,
then they erase history with their "forum cleanup"! :mad:

Anyway, I've invested in an ESR meter, identified about 10 capacitors
that I'm not happy with (although looking at the datasheets just now
while searching for replacements, perhaps 8 of those are reading as
expected, let's wait and see what values I get from the new ones) but
specifically C16 and C20 both give totally bad readings (both read "open
circuit" on the meter) and they are also the only two that have
noticeable brown discolouration around the base. I'm therefore quite
optimistic that this fix may work! They are both 10 μF 16 V 4 mm
diameter caps - about 15 pence each.

I'll report back when they turn up and I've fitted them.
