Con - PM me a mailing address please - I have a few NF2s from my engineering units and I might be able to repair a few more. I'll send you also one of the engineering NF6 boards.
Speaking of which - mostly good news:

I'll have to find out tomorrow what have I messed up with the 6th chip (or it might be just a bad one). I also had to correct several component values, but that was the easy part
With those stats - power usage 1.05A (on a very crappy hub - voltage dropped to 4.1V!), hottest heatsink temp 68C, passive cooling/no fan.
