I see that the AF mod application note at
http://www.elecraft.com/K3/mods/AF_Output_Mod_Rev_A.pdf
is somewhat different to what you describe, Wayne.  The 470 ohm 
resistors appear to be in different places of the circuit.  Does this 
come to the same thing, or are the two resistors from each speaker 
output to ground also necessary?
