Thank you for that write up. I smoked my mosfets but I now have a pair of lead wires to measure bias under the 0.22ohm resistor. I also see you used a 1000uf cap at c5. I was confused by the 2 schematics floating around for this board, where one appeared to show a 220uf Cap in this location. When I get the mosfets I will change out c5 for a 1000uf.
If you got the "prasi board" with diodes instead of led 1000µf is the right value for the feedback capacitor. There are testpoints on the board, never used them, but i remember about...perhaps to measure the 0,22 ohm resistor...
Can't look in the moment, i am using an other pc.
I think i am the only one who made a new board with led. Not tested...
XRK has build in too on his boards he offers. I had uploaded the Excel file with the different boom.

I think you use this board. Take a look to D1/D2 and the R5 22k resisistor connected to the C5 1000 µf capacitor. Because i had little trouble with one board i filled in the values. The testpoints i rembered are not useful i think. XRK will know what to do with them.
