Doubts about choke calculator

I think I posted in the wrong area, right ? PCA would be a computer optimized for audio. In this one it uses a capacitance of 282,000uf (quite high but the original design and so)

Good on the calculator looks like this:
ripple attenuation (dB) 57.6 DC voltage drop (volts) 0.0761
choke L (henries) 0.00475
capacitor C (μF) 282000
AC power 60 Hertz DC current (mA) 10000
DC resistance (ohms per henry) 1.5

I have a 4.7mh Alpha-Core air core inductor so I calculated from it, I found the attenuation half low is good?
 
you worry too much, just go ahead and do it...even without the choke, your data suggested a high power solid state amplifier...

ripple voltage is a function of load current and filter cap, you have very high value filter caps, ripple will be quite low, even without the choke..
