1.It will take exactly the same enery to "fill up" as the same amount
has been removed by the amplifier running with the same current
requirement.



2.However as the capacitance is higher, removing the same energy per
cycle will produce a smaller voltage drop.



3. But because the voltage drop is smaller (2), the angle that the
diodes conduct over will be smaller.



Therefore as the diodes have to provide the same energy as before (1),
but over a smaller time (3) the peak current MUST be higher.


Bear in mind though, that the charging current might be limited by the
transformer impedance.


Tis true, but the transformer impedance will be the same as before, so you would expect the peak current to still be higher than with smaller caps.
