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.
