[Elecraft] K3 external ALC to phono

[Don Wilhelm]

James,

The answer is yes. However, until recently the K3 did not use the 
negative going ALC like is provided by most amplifiers. Be certain your 
K3 contains the External ALC mod if you are using an amplifier that 
provided negative going ALC.

By the way -- Elecraft strongly recommends that external ALC *not* be 
used to control the amplifier power level because it produces excessive 
IMD products.
