They are the USA authorized distributors. They will handle sending it to Schoeps for you. If you wait until they send a whole bunch of stuff if won't cost you anything to ship. If you want to speed it up you can pay extra for rush service.
Schoeps repairs everything they've ever made, and any product that is still in production they guarantee to fix it for the estimate. It shouldn't be too expensive.
Since you have to do this, you might as well send all your other schoeps stuff in...
I had a mk6 repaired recently, cost $250 after all was through. And that's a complicated thing they don't even make anymore.
You should be fine. Call redding today.
