DRD Power Supply
Trying to spec out a PSU for Electra-Print's DRD 45. Just wondering, if the PI filter, and a SS diode rectification, what would be a better PI filter, given they are both using a 20H choke.
1. 100uF + 100uF Oil Film Caps (ASC)
2. 500uF + 1000uF Electrolytic (Panasonics)
Which would have better bass response? Damping? Sound better?

Hard to say. Therefore I would say try them both...see which one you prefer...and tell us.
Generally speaking though..the ASC's should sound better. Because I find lytics...give the sound a slight edginess. On the other hand some panasonics are quite good. And might make the amp a little quieter.
Have a read in this paper...which I translated from DHTROB's website. My translation is not all that good...but you'll catch the drift.
Not a peer reviewed textbook...but I think nevertheless an interesting hands on guide based on experience of an experienced SET amp builder.
