Abstract: A circuit arrangement has a pre-amplifier that has its input connected to an opto-electric transducer and whose gain is controllable by a final control element formed by a field effect transistor. In order to achieve an especially great range of dynamics, the pre-amplifier contains the drain-source path of a field effect transistor that is connected in parallel to a resistor in a feedback branch. This field effect transistor is activated or inhibited by a regulator. In this way, the range of control of a controllable amplifier arrangement following the pre-amplifier is doubly utilized. The circuit arrangement can be advantageously used in optical transmission equipment of PCM technology.

An apparatus in which a plurality of pairs of rollers are arranged in tandem withing a main frame is used to do this. Each pair of rollers can be pivotted about the longitudinal axis of the main frame relative to the proceding pair. This forms a board guide channel that extends in the longitudinal direction of the main frame and which is twisted approximately about the longitudinal axis of the main frame. The boards that are to be straightened pass through the board guide channel and are permanently deformed, which compensates for the twist that originally existed in the board.
