Hello, my name is Noah, I have about 8 walkmans in my collection and I use a dd30 for my main unit. I'm having really bad w&f problems with my dd30, and I'm hoping to find someone in the southern california(inland empire preferred) area who can repair it.
Welcome to the forum, good luck with your search. There was a recent post of a member sending out a unit for repair. Sometimes a good cleaning will help with W&F, make sure the rubber didn't get rock-hard. I also use a magnifier to check for black globs of old belt.
