Howard and all,
 
To throw my observation into the mix, with AF gain full  clockwise and RF 
full ccw, I hear NO hiss while sitting approx a foot and a half  away from K2 
#3810. Its quiet even with earbuds. As I crack open the RF gain,  hiss happens 
(as would be expected). I have plenty of RF gain as the K2's little  speaker can 
be driven to uncomfortably loud SPL's. Maybe some LM380's are  noisier than 
others?
