A suggestion to try
Usually NOS 12AX7 type tubes have thicker pins than new issues. The 5755 adaptors have quite thin pins in comparison. So if they are replacing NOS tubes, there could be bad contact. Try move/shift the 5755 tubes (in their adaptors) gently when in the dac to see if that makes better contact and eliminates the problem.
5755’s are usually extremely reliable.
