Don,

Thanks for the quick response and I was hoping component leads were going to work. I had just cut a few to the appropriate length when your email came in.  I will go ahead and use them.

I will check out the PC trace ASAP.  I did get the radio back together as a 20/40M rig with the shoulder washer in the right place and the lights came on.  Is that a good sign?  When the shoulder washer was misplaced and the power applied, it was for a very short time.  Maybe a second?  As soon as no lights came on, power was removed.  I will take a good look at it under a magnifying glass.

Kieth, 

I commonly use component leads that are lying around my workbench.   
Things are a bit easier if you use the longer ones clipped from 
capacitors, but most any will do the job.  Yes, use solid wire rather 
than stranded so it will support the board. 

Since you powered the KX1 on with no shoulder washer under the PA 
transistor, check the wide PC trace that runs under resistors R16 and 
R17 - it often becomes overheated and will lift from the board when the 
12 volts is shorted.  If it has lifted, cut out the lifted portion and 
do an appropriate repair with wire - that trace runs next to a via hole 
and can short to that via if the copper has lifted.
