[Elecraft] K3 & ALS 600

If you choose not to connect the ALC line you need a way to 
absolutely prevent the K3 from providing more than approximately 
50 Watts of drive.  Excess drive will damage the transistors 
in the amplifier.  You will also be generating a very dirty 
signal until the transistors die.
