Good regulation requires two things: low transformer winding resistances
*and* sufficient capacitance. If the winding resistances are much too
high (which seems to be the case with Steve's transformer) then even
large amounts of capacitance can only have a marginal effect.
This has always been apparent in the old paper charts, and software like
PSU Designer makes it even clearer.
