I don't listen them ,but my power supply is working OK.( power amp 2 bridges channel) I choose them thinking on the Tvicol parameters . Your's are out .
A big question is if quasimodo can have a benefit with this kind of bridge .CX and CS have to match the capacitance of the mosfets ?

I don't know, the pourpose of Quasimodo is to filter the transformer ringing, will be better if you ask Mark directly at the Quasimodo thread.

Looks all right. Except for the mosfet. The one suggested by abanico is a better one. Low Qg

Yes , I too feel, snubbers are for the transformer ringing. So better to ask Mark.

Or better yet, some one to experiment with quasimodo jig if one is having already and test it with LT4320 bridge to see.

Merlin ask yourself to Mark . Capacity of the mosfets is 16nf ... CX must be higher and CS X15 so the values are not the standart ones

Here are some good candidates.
I bought the following transistors from TME (much better priced than Mouser)

IPP040N06NAKSA1 TO220 60v
IPP057N08N3GXKSA1 TO220 80v
BSC039N06NS TDSON8 60v

Regards,
Danny
