Be aware that all non-closed coils are microfonic relative to the earths magnetic field, and there is nothing you you can do about it, but a closed design (toroid) or a mu-metal shield. This is more pronounced for cored coils than air-coils, because all core materials has magnetic hysteresis. The effect is usually ignored, but I wouldn't be surprised if it showed up for time-nuts...
