I actually did check the fuse- I assumed it blew because there is absolutely no power to the unit when I turn on the power switch. It I read correctly, it is a 250v 2A fast-acting fuse. I got some replacements of the same type from Radio Shack, but each time I put one in and plugged in the unit the fuse would blow immediately. There is a difference between the two - the one in the recorder had colored bands on it, and the one from Radio Shack was clear. This may be purely aesthetic but I'm not sure.
