[Elecraft] K3 AF Upgrade Kit (for speaker amplifier and LINE OUTs)

The document is accurate.

It means the speaker amplifier, which is used to drive the internal 
speaker and the external speaker jack. Not the headphones or LINE OUT, 
just the speakers.

There is a separate stereo amplifier which drives the headphones.  Front 
and rear headphone jacks are driven from the same headphone amplifier. 
These jacks are driven only by this amplifier.

There is a separate path not using the speaker amplifier or headphone 
amplifier that drives the LINE OUT, and only the LINE OUT.
