Dear All:

We have problems with our two Bruker cryoprobes. One probe does not response to proton tuning/matching, but the other channels (13C, 15N and 2H) work fine. The other probe has unstable lock level. One when the gradient cable is disconnected can the lock level remain calm.

I am wondering if anyone of you had similar problem and how did you fix it. I appreciate all feedbacks.

Best regards.
