After many hours of editing here is the video of my install.
There is a comparison at the end of the two systems. This was tricky to do and on the microphone it's tricky to tell the improvements.
On listening while shooting the video the old system was just short of distortion and thus was the level of DB i set. While the new system had far more warmth of sound at that DB level, but was just ticking over.
I hope you like it guys. Its been emotional.
