RE: Help with CCS ?

Figure I'll follow up on this.

So the new mosfets, resistors and caps arrives (thanks Kevin !!!), so I replaced everything, and still, nothing was working. I figured the last item remaining was the pot, so I removed it, and tested that it still worked, and it was fine (range was 4 ohm to 1.01k).

I'm at a loss as to what else could be at fault. When wired up, exploring the full range of the pot, I measure 2.9V (min) to about 3.9V (pot at max) across the 130ohm grid resistor. Strange thing is, the heatsink is notably cooler than the other three CCS's, I'm guessing doe to the fact its not dropping as many volts.
