Ok, dumb question here. I recently blew a fuse in my Sony S7700. It is a 2A/125V 5mmx20mm fast-blow fuse. When I went to my local hardware store to get a replacement, they looked at me cross-eyed like "where the heck did you get this fuse??" (and they are normally very good). I have checked a bunch of online sources (eg. partsexpress.com, acehardware.com, etc)....and no one seems to have this particular fuse.
Anyone know a good place to get these things?
