Hi all,
Just wanted to say thanks for the feedback on this, problem
solved. Checking under some pins at U3 revealed a short. All is well
now, and it's on to building the RF board, Part I.
Thanks again,
Will

Just got myself a K2 (yay!) as it sure makes for a very nice rig and
kit to build.
I've just completed the control board, front panel and the minor
assembly on the RF board. Upon power-up, there's NO smoke (yeah!) but...
I did notice that the area of the control board where U3 is located seemed
hot. At first I thought this was attributed to the regulators directly below
it. Instead, I'm now feeling (and I mean feeling!) that U3 is pretty hot. I
managed to just run the DISPLAY test to fetch the voltage and saw it show "E
17.8 i .68"
Now, I did test the power supply, and it's happily putting out 13.8V all the
way through the RF board. But it looks like a simmering U3 and the display
are pointing to something wrong with the voltage and current sensing
circuitry. Am I on the right track?
