what does L5C17 do?
the centre tapped transformer cannot drive the dual rectifier PSU.
What if the currents from the two rails are not identical? Eg driving a ClassA push/pull amplifier.

I think it is to suck out the ripple in a certain freq band 😉 , (2kHz?) although the two 3mH coils are in series and could be replaced by a single 6mH. Of course then the diagram doen't look symmetrical anymore.😀

BTW Is there a special reason to use two bridges instead of one?

The unit i will be using has 2 independent potted 3mH coils in it 😛

Ease of implementation and use + the fact that i would know if one of my rails goes out its a simple and cheap replacement ( eve though it wont happen as i will be using 50A bridges )

A well designed amp is as good as its power supply!
In the end you can only make as much power as the power supply puts out.

Working on PS Rev 2 as of right now...
