This Marantz receiver is out of my personal collection, it was a one owner. The receiver has been serviced by a tech with 40 yrs experience, the pots have been cleaned, bulbs upgraded to LED & a basic cleaning. The receiver was sold new by my families HiFi shop in the late 70’s & i purchased from the original customer. It sounds incredible and works like it should. Everything works but It is vintage and is in wonderful condition so it’s sold as is. The plastic cover on the back for the Dolby option is missing, it doesn’t affect anything and it’s a cosmetic issue. Please feel free to ask any questions you might have.
