[Elecraft] how to bypass atu?

As usual Don has provided the correct direct answer to your question.   
However, I'm wondering if it would not be desirable to keep the tuner in the  path 
to the amplifier.  I believe it will assure a measure of additional  filtering 
for spur suppression and match the amplifier input exactly.  Just  a thought. 
 I don't think there is a down side to keeping the tuner in the  circuit.
