Those things are pretty hard to open up............I had the roughest time
with the one for my FGR100, but if you are careful, a utility razor can do
the job. Gluing it back together is another thing. Probably, the safest
adhesive is epoxy. There are better agents (Methylene Chloride), but these
are very dangerous.

power
supply can be made to be quiet. Connect .01uF caps across each of the
rectifier diodes, and bypass each leg of the power transformer's
secondary
to ground with 1uF non-polarized caps to ground, and you are all set.
Make
sure that you derate the 1uF units to at least twice the peak to peak
output
voltage of the transformer.
There is no such thing as a good wall wart, from Radio Shack or anybody
else. Even the relatively expensive Power One frame supplies need these
add-ons. The reason that these manufacturers don't do this in the first
place is because they don't have to subject their units to stringent EMC
testing.
I hope this helps.

Pete,

What is your preferred method for cutting the wall wart open?
