Here is a link to a guy in my area, I don't know him, but I know of him and has a reputation of doing excellent work. He completely rebuilds vintage gear and offers them for sale when completed. I have contacted him and he is going to rebuild my Marantz 1060 this fall. Also, check out his sold listings.
