    I recently rebelted this 3-piece boombox and I was going to shoot a video of it & as I was checking it out for functionality I discovered that the tune indicator traveled in one direction and then the pointer stopped moving but the radio kept tuning in stations from one end of the band to the other with great sound.
    The pointer is moved back and forth by a thumbwheel that drives a Plastic flat gear ribbon that is flexible to make a ninety degree turn near the thumbwheel to travel back on the side of the thumbwheel back into the side of the radio.
    This Plastic ribbon has size of 4 mm wide, about 2 mm tall with teeth and is about 250 mm long if it was all present
    Upon opening the for the first time weeks ago I did not observe anything falling out of this radio, so it is a mystery as to where this broken piece went to.
    Does anybody have this radio as a parts box?
    I am searching for this part does anybody have this that they would be willing to give to me or and or willing to sell me this as I will then buy this part, I have paypal.

    I have two RX-C46F and I used cable tie as the flat gear rack which is fine (remember to buy the thick one - I used 8.8mm width and 40cm long one --> thinner cable tie doesn't work because the gear rack tooth not match with the gear)

    Yeah that's an interesting fix idea.

    There used to be one kind of 80's or 90's kids plastic gyroscope that use a long plastic pull cord with teeth down one side. And those pull cord helicopter toys where one pulls a plastic strip with similar gear teeth down one side. A few hours intense searching on e-bay may bear fruit along these lines.

    EDIT: Went searching and found "timing belts" and "gear belts" in similar narrow sizes that could be cut and opened out etc.,

    Yes, I went to many toy stores looking for those pool pool devices that would spin something up and use a tractor tooth but none of them were viable. So in my instance I have so many boomboxes that I've given up on trying to repair this c-46. So if anyone's interested in a perfectly working very good condition with the box this model it's just the tuning works but you can't see what the indicator is on what channel it's on. So send me an email and I'll sell it to you cheep. decentman4you2007@gmail.com I'm in Dallas Texas by the way.

    While I was up here and I just remembered I have this box here and I was taking a picture of something else I thought well here. Let me show you just a quick ie picture of this very same model in the box. Well box I'm not getting it out again right now but it's in. 17186495630083007400110377921945.jpg
    Yeah, there's a few other models up there along with the marantz. Anything else you're interested in? Just 0. 2. And look at that it's spelled out. 2. I said point to I talking to the phone. decentman4you2007@gmail.com
