Go to the Autoharp Page and join the Cyberpluckers list. They share info on all things autoharp. Let them know where you're located and likely you can find other 'harpers nearby who can help you. There are also links to autoharp luthiers on the site.

If you're interested, you can check out my "Hymn of the Week" autoharp instruction videos on youtube under user name Minstrelcraft.
