[Elecraft] Need Help with XG1

[Joe Planisky]

Have you checked for any damage to the circuit board traces?  If  
enough power was applied to "fry" those resistors despite D1 & D2  
being in the circuit, maybe some of the traces were damaged as well.   
I would think it would be visually obvious, but maybe not.
