ok, The LM317 claims a ripple rejection of -64db…which for a 15V output supply would result in 20mVpp ripple if I got it right.
With a simple LC using 170mH and 200mohm choke and a 50000uF cap after that I will get 6mVpp…
…so a simple LC instead of a LCLC should be enough ?
That is something I can easily test as all the components are in the house…
