I am trying to repair this Walkman and I believe the motor has gone on it. I replaced the belt already, but when I hit play it makes a screeching sound with nothing moving then stops and then the reel spindles move for a second followed by 3 beeps. Googling that motor code I couldn't find any replacements, but I also looked at a ton of cassette motors and cant find any with that specific mounting and lug patterns. Does anybody know where I can find a replacement motor of any sort or am I sol?

Thanks!
