Sorry, never seen one, is the back label in Japanese, I don't think they sent any over here. I think there might be one or two owners on this forum but they haven't been around in decades. The unit should be mostly similar to the Marantz/UNIX PMS-6000 which has the turntable. I've never cracked mine open so I have no idea what the size is. Most of the time, the manual does not tell belt sizes. Here's a link to Turntable Needles, they have the sizes (for the PMS-6000) and I've ordered from them with good luck. https://www.turntableneedles.com/find10.asp?manfg=MARANTZ&modelname=PMS6000&Select=Model
