try dumb vertical scaling of inverters

Browse Source 
it seems that if we take a non-inverter than has y(0) *close* to 0, and
scale it enough, then we get stable transfer.

this suggests we really just want something with a massive number of
couplings (to keep the coupling ideal) and enough asymmetric windings to
get us > 1.0 tx ratio over some range.
