Don't know if they will have your exact unit, but they do have a whole page or two of replacement remotes in their catalogue. You can request one by mail or look online. I've gotten several deals from these folks in the past. If you strike out with the remote, at least you may have a new source for Electronic "widgits" and the like.
Check out MAT Electronics. I believe they are in Pennsylvania.
