Yes Willib, the D92 are dual 20A 200V diodes.... 40A per package. If you get the wave correct the fets stay cool, but the diodes get warmer than the fets, so they are paralled to keep the heat down.
Your scope looks better, but it looks like you still have slow diodes on it. If you dont want to pull the to220 types out of a supply, use one or more of the fr155 or similar which will be on the computer psu's as well.... not the input diodes which if not bridge, will probably be 1n4004 etc.... slow ones .
Circuit..... then it might look like I know what I'm doing... can't have that...
Just line up the overlay with the board (track) diagram.... better yet, download the .pcb file and a copy of autotrax or easy trax or protel latest offer, and use it on screen then. You will then be able to use a composite to view. (tracks and component overlay concurrently.
