Hi Dennis,

Regarding AGC OFF -

If you plug your headphones into the speaker jack, you can 
use AGC OFF and turn down the AF gain, and avoid hitting the 
K3's limiter. I have a little network with a small amount of 
attenuation to cut down on background hiss. I also have back 
to back 1N5818 Schottky Diodes across the headphones for 
hearing protection. The diodes introduce just a little fuzz 
on the loudest signals - nothing like the gross distortion 
caused by the K3's AF limiter.
