[Elecraft] My God, what have I done?

[Ward Willats]

Thought I'd like to lower the AGC voltage on K2 #3578 which has been 
working FB since completion a couple of weeks ago -- but volume/band 
noise would come up a good deal with AGC off, so thought I'd back it 
down some...

Adjusting the pot -- oops, dropped my jeweler's screwdriver. Hit the 
RF board between the diodes and right edge of the case.

There was a spark. Rig dead. Switch off instantly. But wait, now 
smoke, heat. Pull power cord. That stopped it.

Screwdriver probably shorted aux 12V stake pin to ground I guess (I 
put the KPA100 connector in "in advance"). Or messed with D10, D12 -- 
not much there.

Looks like the 8V regulator is cooked -- probably where the smoke was from.

I'm so depressed and angry with myself about this I think I'll go to 
bed before I get into the liquor or firearms. But thought I'd whine 
to the list first and share my pain. I hope you'll all tell me only 
and handful of power supply parts are toast, and not every other 
component on the control board....
