when using a 31000µF cap and a 1,1mH inductor i calculate the resonace frequency to be 171HZ and here where i live the retified DC will be 100HZ is that good enough margin to not excite the hole PSU into resonance...i guess i will know pretty soon but it would be nice to now your opinions
btw there will be CLCLC filter all caps and inductars as above...or maybe CLCLCLC with a 1µF cap first to limit the current spikes and protect the diods.

This is a real effect, but I recall working it out once
and the "Q" of such a circuit is an F*L/R figure, and because
the L is only a millihenry, the Q is quite low.
