This capacitor value also affects the behavior of the speaker amplifier 
when headphones are inserted/removed.  The present value was arrived at 
after a lot of testing with the Field Test group prior to product release.

Many years ago I developed the habit of always turning AF Gain to 
minimum when I turn any radio off in my ham shack (or media room, 
or...), and ensuring it is low before turning any radio on.  Like 
wearing a seat belt, it's probably not necessary -- but then comes the 
one time you're glad you did :-)
