Welcome to BeoWorld, Tom!
While I would hate to speak on behalf of another member... There is a fine gentleman in your general vicinity (South of Brisbane) who has done some brilliant work on 70's and 80's B&o -though perhaps not specifically on your BC7002.
I might suggest sending him a PM/email via the site here. His UNAME is: geearr
Perhaps he may have some interest or could point you in the right direction.
BTW, the BC7002 is a wonderful piece and well worth the effort to bring back to its former glory!
