The single best place to start reading is the First Watt site.

Download and read the F5 manual. It explains in large detail how it works and how it can be configured.
The cascoded part is nicely described on the F5T article that again can be found on the First Watt site.

I guess the 'F5 Turbo' article is the best 'summary' of it all

Dantimax.com boards
at Mikkel's prices can afford to use two boards per channel
though Im not a fan of those screw teminals
and 10A may be a bit on the low side

Tinitus, I have the universal power supply board, it has several things I don't really care fore 1) rectifier section, 2) power-supply caps if using 8 are 30mm diameter and 3) the screw mounting holes are to close to the caps so now a 25mm almost becomes your max diameter. Ideally I would like to see something like the "Chipamps.com" Aleph psu boards but with 8 caps @ 40mm..... This is what I'll probably end up doing > Click the image to open in full size.

now you have bought bridge kits, why not mount caps on proto martrix board, and wire it with solid core copper wire ?
most likely even better
