Hi, new to forum and hoping for some help. Just found an aiwa 955 radio that some one was discarding. Brought it home to find that it works well enough as a radio, but the cassette deck has no motor function. I’m guessing it needs new belts from my quick searches-is there any help in deciding where to look for the right belts? Also the volume knob is “scratchy “- any advice for how to correct that? Thanks, I’m new to this but it looks like a really groovy radio and I’d like to give it some new life!
