Choke filter question

[Helmholtz]

Output ripple depends on input ripple.
Input ripple at the 100µ cap depends on total DC current.

Thanks. Still I don't get it. If I replace the choke in B circuit with a 100 ohm or 1k resistor the ripple after A choke remains almost pretty consistent . The problem is just when both chokes are connected please. Each rail works well connected alone. Each rail works well both connected, when one is LC and the other RC but goes crazy when both are LC connected. So the DC current is the same if I use LC (A) / LC (B) or LC(A) / RC (B)

I suggest monitoring the ripple voltage at the 100µ cap as well as DC current in each branch when doing changes.
