[Elecraft] K2 DOA at second power up test

[ke4d]

Ok, I've done a lot of dumb things in 37 years of amateur radio but when
constructing my second K2 a few weeks ago, I dropped a piece of component
wire on the RF board while doing the second power up test on the receiver. 
Bam, no power at all, no lights, no relays nada.  I thought I blew D10 on
the RF board but Elecraft tells me it leaks anyway. I changed it
nonetheless, no joy. I get 12 volts on the main bus on the RF board until I
hit the power switch. Then the voltage drops to 2.5 or so.  I lifted the 5
and 8 volt regulator output leads, still low voltage there.  Changed them
also but still no joy. I'm at a loss where to look next. I cannot find
anything that warms up, looks bad, measures the wrong resistance, just low
voltage.  Low enough that the relays don't activate and the display is a
dismal green with no power to it. Any suggestions other than buying another
Icom or Kenwood?  I could say the rig is KOA instead of DOA since I killed
it!
