Since I'm still in the process of building, and will likely finish this 
weekend, I am curious whether or not to do this replacement on my KX1.

How many KX1 builders have noted the low power out and made the change 
described below?  I'd rather "replace" it before installing it  <grin>  
And I can buy the replacement tomorrow.

TIA es 73, Phil
