Ian,

If you have time/inclination, I'd be interested to see pics of your
dissassembly/reassembly process.

I hear you David!

I thought I'd start on the working filter and the repair the smoked unit
when I know what I'm doing.

I've burrowed inside the filter and was surprised to find the filter caps
(WIMA MP3-E) are only rated for 250V.
The MP3-E is a discontinued line (read: I can't find a datasheet).
These might be ok for European 220V, but my UPS shows my line voltage to
average 243V, with regular excursions over 250V.
These caps may be good, but I'd like to see a bit more margin there (it'll
be going back together with MP3-X2/275V caps).

Robert, while it's not that I don't value my time, my workmanship is up to
the task, and I'm reluctant to replace a component (possibly with one no
better than the failed part) when I can fix it better than it was in the
first place.
