Just to pile on, I too would like to somehow see 100% proof that there isn't any hidden coil anywhere, as I'm not sure that's been fully ruled out yet - as truly unlikely as it seems. For sheer curiosity more than anything.
With that being said, the fact that the things don't actually buck any hum is fairly decent evidence in and of itself. I feel like that aspect might actually be getting lost a little here.
