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!
