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.
