This mod is only recommended if you do not exceed 5 watts.  It makes the final
slightly more efficient, which only matters if you are operating on batteries. 
I don't recall for sure, but I think it is only for CW, not SSB.

The mod doesn't seem to be on the Elecraft web site any more, and I think it's
not really a good idea, even if you are a QRP only op.
