can magnepan mg II a's have

Replace the fuse anyway, even if it doesn't look blown. If you still have no tweeter cleaning the straps as Elizabeth suggested can't hurt, though beyond that you will have to open up the speaker, or send it back to Magnepan for refurbishing. Sometimes the wire traces corrode over time.

Magnepan does not do a refurbishing on the II's anymore. However, you can purchase a kit from them. Perform a search here and at audio asylum to see what you will need to do if indeed they are damaged.

I hope you or your son are handy and good with your hands. You'll see what I mean once you do the search.
