Elecraft has warned NOT to listen to that advice .

The K3 ALC could only get worse and misbehave when the slow 
loop from an amplifier is added.

Has anyone actually measured the combination of a K3 and the 
SPE amp
connected and adjusted as suggested by SPE? I have run my 
setup without ALC,
but I am curious about the statement and what the real 
results are.
