(for a Green Preamp)
I've gutted a Digidesign 442 box, and kept the switching PSU (+15,-15v). The removed old circuit board had two coil/chokes on it where it recieved power. I'm keeping/reusing these, but a friend of mine suggested adding two caps after the coils, both tied to ground...as added filtering.
1) Does this seem applicable?
2) Is there a specific name for this filter?
3) What value and type could these be?
4) Most importantly, how do I place these, POLARITY-wise ?
(. . . dots mean nothing . . . . .)
