[Elecraft] K2 - Time on K2 Finals

[Don Wilhelm]

John,

I don't know of any lifetime issues with the K2 finals or any other 
transmitter with a solid state PA.  That was an important consideration 
with tubes, so maybe it was just an "old school" statement.

The K2 PA transistors are quite hardy, but if one abuses them 
sufficiently (for instance transmitting into a high SWR at high power), 
they will turn "belly up" in short order.

73,
