I’ve seen the TV ad for Marriott Courtyard with the seen that includes the frame above many times but, do not know which Marantz receiver is on the shelf in the background. The pic is not high enough resolution to make out the model number when blown up either. I own some vintage Marantz gear but, am not familiar enough with their receiver lineup to tell by the front panel layout. Okay Marantz experts, help me out here!!
