More fun & games in transformer winding land, where up is down, and down is out. Cut a lot out also the video editing software was playing silly buggers, so apologies for glitches.
I was going to say the same thing. Andy, I hope you don't effectively have a big fat shorted turn in the electrostatic screen. Don't worry about the thickness of the copper foil, window space is more important. It's really as the name says an electrostatic screen to screen noise on the mains. If there is a fault to it then there are bigger problems and the primary fuse should blow anyway.
