MARANTZ 4240 QUADDRAPHONIC RECEIVER Marantz - 4240 in original condition! Look closely at the pictures as they are included in the sale. Please note that she is in original condition. We do not make any warranties on vintage electronics and collectibles as this will require ongoing technical care by a trained qualified service technician to protect her. I was going to do it and keep her but unfortunately I have run out of time to do everything and think her next owner will get the joy sooner. Once this item is sold it is final. No returns are offered due to her weight.
