I was wondering if it would be possible to build a surge
suppressor to eliminate voltage spikes from a refrigerator.
There is apparently only one power line running throughout
my dorm room for all of the outlets, and the refrigerator
(small cube type) spikes my stereo system every time it
turns itself on/off.  We have hooked up the system through
as many as four (cheap) "full protection" surge suppressors.
Is it possible to upgrade the MOVs inside, add some in series,
parallel, or something like that, or do I need to be adding
chokes/torroids/RFI filters?  I haven't been able to find
any project books detailing how to build something like this,
so any recommendations on even theory type books would be
appreciated (not the kind of stuff they teach us about in
circuits classes).  Thanks for your help,
