[Elecraft] KPA100 diodes blown...

[Brett Gazdzinski]

I turned my K2 on after is sat a while, and hit the tune button to tune the 
antenna, and got crazy indications, D16 and D17 in the KPA100 are blown.

Is there nothing that can be done about these diodes blowing so easy?
I need to order a set from Elecraft, but I leave all the other radios hooked 
up and nothing blows in them...

I disconnect the antenna's, and select the dummy load, plus I usually have 
the homebrew receiver selected which has a 3 turn coil as an antenna input, 
which should look like a short to any voltage, but enough voltage must get 
through everything to blow the diodes in the K2...

How are other radios protected against static buildup on the antenna?
