Let me be sure I am correct in my calculations.  Choke input (5 - 25 H) 
with 4 mfd filter will allow about 5% ripple.  Now, when I add the 
second choke (5.5 H) and the second filter (2 mfd) is this now 
calculated as a capacitor input for this last stage?  If so, then it 
would result in another .15% reduction or about 3.3% total ripple.  Is 
this correct?
