[Elecraft] Dead K2

[Don Wilhelm]

Kristina,

It sounds like you have created a short in the DC power and the 
resettable fuse is being activated.

Check all your soldering and the pad placement of the thermal pads for 
the PA transistors.  Did you check for a short at the collectors of Q7 
and Q8 as instructed?  If so, what was your resistance reading.

73,
