I fixed the low power issue. It was down to the thick wire I had going from the Neg terminal of the power plug to the rear chassis bolt?? Anyway I removed this and power jumped back up.
The audio is a separate issue. As I said, I believe it is audio and not signal related as when it drops out I still receive signals only much quieter. My board is a later v3 with socketed audio chip. I wonder if I tap off the back of the volume control to a separate amplifier??
