OSU1 Power Amplifier Module, Circuit Diagram

Colin Arrowsmith has traced out the circuit diagram for the 'OSU1' power amplifier module used in the Series 632 and 634 tape recorders. This was a transistorised amplifier module, from 'Newmarket Transistors'. The module uses germanium transistors which may now be difficult to obtain, so some modern alternatives are suggested, although they have not been tested.
