All P-N junctions become noisy under circumstances, particularly when they're driven in their Zener region.
I would say that a diode that has done its job of protecting a low-noise circuit should be replaced one day or another.

Never noticed anything like that with my traveler MK3. Then again, I use
it mostly for recording... errr... noise, i.e. street scenes and
industrial ambiences.
Are these diodes in the mic amps?
