We tried to open it up but we can't reach the malfunction. We can't find any tech specs as well.

Does anyone have specs or more information on where to find replacements for these? See pictures attached.
Pretty sure you can get Beyerdynamic transformers that are straight plug-n-play substitutes for the MCI's.

Hope this helps...
