This patent describes the so-called "cascomp" amplifier − see John Addis, Good Engineering and Fast Vertical Amplifiers, in Jim Williams (Ed.), Analog Circuit Design: Art, Science and Personalities (1991), p.107+
According to Addis,
[the circuit] was used extensively in the 2465 to reduce the power requirements by increasing linearity for a given standing current.
