To be fair, W8JI usually slowly moves himself off his always/never
rail position to a more reasonable often/hardly-ever position. Some
time ago, he and others on this newsgroup asserted that absolutely
nothing changes when one moves the balun from the tuner output to
the tuner input. The subject came up recently on eHam.net.

If you draw a floating network on paper and look at what happens,
you'll see moving the balun results in the same stress on the core
regardless of the side of the tuner the balun is on.

i.e. a paper solution indicates that nothing changes, but ...

In real life, stray capacitances from the network to ground modify
the behavior of the system when the balun is moved, but the change
is generally both small and unpreditable.

i.e. changes can and do actually happen in the real world.

As in any distributed network configuration with reflections, if the
balun changes the phase between the forward common-mode current and
the reflected common-mode current, that can shift the location of
the common-mode current nodes.
