I think you're talking about the tinsel leads. They are repairable to an extent, depends on how bad they are. They can be soldered together or super glued to whatever if need be. It's worth a shot. And no, SoundAdvice does not repair equipment in house, however they may be able to send it out for service. I'm not too sure how that would work though considering they no longer carry MB Quart.
