This may help.
The units work out of the box, and there are many here now. They are solid as all get out, and folks give them a real beating..... they don't die.
Many folks seem to make changes, and they suffer for it. As built, they are seemingly bullet proof.
Tiny, 56r will over heat and kill the fets in my experience.... 5r6 is fine.
Been busy, and didn't notice this thread was alive.
will take any questions you may have.
Oh, and I use an 18v zener instead of the 13v zener, and that may help with gate drive voltage. Check your turn on voltages, they may be a bit low perhaps. other than that I can;t see any difference. I used that gerber for the last boards I got done.
What is not shown on the boards, is that the 8010 has pin 6 raised out of the board, and is used for on/off. The pin does not go to the control board, but is isolated from it as it sticks up not down, and the pin is used to go to the 5v or ground for on / off. If left floating it will go on/off erratically... not good, but generally does not kill anything either, just unstable.
Remember too, if you use a starting resistor to get the caps charged, you will have to reset the chip. or it will hang dead. I reset by shorting the 120r after the resistor to ground with a push button... rough, but works just fine.
You may just see the pin 6 sticking up here.
Also check you have not got any dry joints with soldering the 8010 on the daughter board
