Going back to Mark's H9KPXG...
I am building a Stasis with ZM's boards for 50V rails (thread `New Stasis front end'). There are many threads the Pass Labs subforum on PSU filter configurations; CRC, CLC, pi filters etc., the consensus would appear to be that CLC might be a good way to go. Something like 44mF - 10mH - 44mF using a Hammond 159ZJ choke in place of the typical parallel resistors. I'd also like to leverage the latest variant of the F5M power supply board which has places for 4 caps after the bridge rectifiers for each rail (so 8 in total; 4+ and 4-), and subsequently 4 separate RC cells; one for each rail and for each channel. I'd like to swap in four 159ZJ in place of the CL used on the F5m. So as to end up with 88mF - 10mH - 22mF on each channel/rail with the LC being four independent legs

However, if I stick 22mF (63V DC rated) capacitors everywhere, then from the first post on this thread, I end up with an inrush charge of >250J (=0.5x12x0.022x50x50) which is beyond the capacity of the optional largest CL (which I have used in building this board).
I could perhaps use the shortest time delay and just use Mark's circuit to `take the initial bite' out of the inrush surge, but this doesn't appear (to me), to be optimal.
I could perhaps build a pair of boards and supply each channel with its own delay board, but this seems a bit `overkill' and not the most intellectually elegant solution.
Another option might be to add the chokes as planned but leave a CL in series with each choke. In this manner Mark's H9KPXG board would address the inrush associated with the first 8x 22mF caps and the high initial cold resistance of the CL would mitigate the impact of the additional 22mF sitting on each channel/rail (4 in total). A small amount of resistance in series with the choke may also assist with managing any tendency for the LC filter to ring. Something like NTC B57236S0229M000...
Does this seem a reasonable approach and/or are there better solutions - please educate me.
thanks
