[Elecraft] K3S issue

[Dave W8FGU]

Matteo,

I had the same with my build years ago. Turned out that I crushed one of 
the driver transistors while seating the amp. You might check that. I 
believe it is located near the rear panel.

I was able to straighten it out and get it working until I received a 
replacement from Elecraft.

73,
