[ARC5] Carbon cartridge replacement circuit

>Just as with an ordinary valve, a carbon microphone amplifies by 

mediating the flow of power from a source to a load.<

First time I heard someone assert that a carbon mike was an amplifier, I thought "Whaaaaat???"  Until I thought of the mike button as the analog of a grid controlling a current flow.  Of course, we could then philosophize over whether is it absolutely correct to call a tube an amplifier, or is it only a key element to an amplifier circuit?  :-)
