I have never noticed slow variations in output during normal operations on my K3. However, the other day I installed the external ALC mod. During the testing step I connected and disconnected a 9 V battery with a series resistor. It took a couple of seconds for the K3 output to change. Seems like another reason not to actually hook it up to the amplifier.
