A couple of years ago, when trying to use the K2 as a receiver with a homebrew transmitter for Straight Key Night, I accidentally transmitted about 12 or so watts directly into the front end of the K2/100 for over 30 seconds. The K2/100 isn't apparently any worse for wear. So, it would take a considerable discharge to cause a problem of this type.
