I'm not sure what the separation usually is. =20
I've had similar thoughts about shield cans on inductors.
Not much documentation out there on those subjects.

I was winding a small coil last night, about 800T of #30 on a 3" dia glass =
tube.  Had time to wonder..

Should be interesting.   I'll be using a nice stainless steel gazing ball f=
or my topload.=20

The amount of magnetic flux coupling is probably not enough since there is =
no core material and (I think) the top load is usually separated by a few i=
nches from the end of the autotransformer.
