This Sansui G-4500 is exceptionally clean and well maintained. The receiver was professionally refurbished on 9/22/26 with documented proof. Everything works as it should.The G-4500 is highly sought after because it only contains three IC chips in it's design which makes it highly desirable in the vintage market. All Sansui receivers built after this contained many more IC chips. When an IC chip fails on a vintage tuner, they can be near impossible to replace. All three of the chips are in the tuner area on the G-4500 and if all three were to fail, the the amp and pre amp will continue to work fine and unaffected. This is important to know for long term ownership.
