If it was given to you for free and you have a potential use for it, I'd consider having it fixed locally. Even if it's rated at just 60wpc, it'll pretty much fill any normal sized room with good sound when matched with decent speakers.
I know a guy in Tampa who can surely fix it for a reasonable price.... His name is Ted and his shop is called Audio Laboratories on Henderson Blvd. It would probably be cheaper to find a working one on eBay, though.
Did you do any research to see what they sell for on ebay in working condition? IIRC, while not as desirable as the TOTL big boys, the mid and lower Sansui G-series receivers are also somwhat sought after. Not everybody needs to have triple digit wpc and the look alone is worth hooking up some speakers.
Good luck whichever way you go!
