Manley Ref C new Tube help

Hi Guys, So for those of you who are much more tech savy then me maybe you could help me out.

I recently replaced the old Sovtek 12AX7 tube inside my Manley Ref C with a Telefunken Black Diamond series 12AX7. I've changed the tubes over but am now getting no sound into the computer. I swap the tubes back over and it works fine.

Any Ideas?
