[QUOTE="handsome, post: 1027415, member: 772"] its basically an automatic bias circuit - at its simplest: a small resistor in the cathode of each output tube is used to measure the current through each tube, the current through one tube would be used as a reference a comparator (usually an opamp) then compares that reference to the other tube(s) and adjusts the bias of the other tube(s) as necessary.
