K7 is a great sounding capsule. Send it back to Ben for repair. Order something relatively cheap to use while it's gone. If you can order a 3U or Maiku, you could even prefer it in the end. If you're thinking about another K47/M7 build in the near future (M49, etc), order a Heiserman M7 or something else high-end. Gives you the option to swap between them to find which capsule you prefer in which mic.
