This control device consists mainly of a resistor bridge, which comprises the manually adjustable resistor 54 and the balancing resistor 56, which are designed as a potentiometer. Two trimming potentiometers 58, 60 and 62, 64 are assigned to each resistor 54 and 56, respectively, with which the voltage drops at the setting potentiometers can be adjusted in such a way that a setting range that is adapted to the operating conditions is obtained. The power source, e.g. As a battery 66 is joined adapted to the diagonal of a Brückensehaltung while connected to the other bridge diagonal of the servo motor 38 via a Grleichspannunga-Yerstärker is _o This amplifier comprises two transistors 68 and 70 whose emitters overall * jointly at the collector another transistor 72 lie. Two transistors 74 and 76, which act as emitter followers, are assigned to the two transistors 68 and 70. The amplifier also includes resistors 78, 80 and 82, 84.
