In this video community member Matt Blue AKA kcatthedog shows how he has modified the transformers in his JRR Panther Active Ribbon microphone with a CineMag 9887 transformer.
The video is extensive and shows all the steps necessary to make the modification. Matt also shows the challenges he faced during the process and how he overcame issues of fitting a different sized transformers.
During the video the audio swaps from left to right on purpose, all is revealed as why this happens at the end of the video tutorial.
Thanks Matt for making this video. Watch it here
