I also vote for fixing it. The SX-1050 was one from top of the line in what many think were the best built receiver series Pioneer ever made. I have it's big brother the SX-1250 which I fully recapped, and its a very nice receiver.
If you go to the AK board, they have a Pioneer section. The folks there can reccomend some good techs who specialize in vintage Pioneer - there'a guy called Mark the Fixer who has a very good reputation (I've never used him, but I've met him and he seems like a straight shooter).
