actually, thinking about it, my neighbour was complaining that his alarm clock radio thing was emitting lots of humming and had i got any electronics in the room that backed onto his house...
i went with "i have a few bits and pieces, but nothing major."
none of my migs have shielding, but i think i might take the time to put it back if i can fit it. plus this may resolve the moving spots on the TV i use for one of the A1200's...
