Saw it. In a radio where I already split off the AVC function off the
audio detector,
I'm trying a fixed positive bias of 300mV on the "bottom" of the volume
control.
Simulations indicate lower distortion on many various levels of carrier,
and it seems
borne out in an actual set. But the only cap I'm working against is the
coupling cap
between the volume control and the 12AV6 grid. Which is essentially a
fixed value.

I'll give it some time and thought to be sure that this is in fact a
good thing or not....
