Oh come on! I just finished this... At least I haven't done the drilling. Please tell me boards are coming soon!

Nice work as always Salas!

Keep in mind that the board design and C3's cap choice are critical. Thus the 100kHz ESR note (coming from real tests on the LCR meter). I have already proper C2 & C3 suggestions from Panasonic and Nichicon to propose.

I havenít seen a Quasimodo snubber before, I am as looking at the caps before the rectifier and thinking what the? Can this be done with other psu designs and what are the benefits, less ripple?
