Amen to that, brother!
After 50+ years of building radios, I built my K3 very carefully.
However, on completion, the output was very intermittent. Tapping on the 
cabinet would trigger the problem. I tried everything, including on line 
and on-the-phone discussions with the Elcraft service dept.
Finally, I boxed it up and sent it to the doctor.
They diagnosed the problem right out of the box, with no tools.
I had placed two lockwashers on the wrong end of the screws holding the 
driver transistors to the bottom of the case, so they made only 
intermittent contact. Bingo! Was my face red!

The moral of the story: be careful, and check EVERYTHING during assembly.
