I'm still pondering the grounding block.


Some years ago a couple of plumbers told me they had been to a house and in the loft was a bucket of sand supported on a piece of wood across the ceiling joists and in this bucket of sand there was a foot length of copper pipe with an earthing clamp and earth conductor attached to it that was connected to the front bedroom light fitting to earth it.


I suspect that is as useful as the audio grounding block in the link.
