Power Darlingtons are used in common-emitter con-figuration to give high current gain for driving control phase of 60-Hz servo while providing high input impedance for preamp. No trans-formers are required. Darlingtons require heatsinks. Suitable for driving size 11 servo at 4 W and size 18 at 10 W if emitter resistors R7 and R8 are changed as in table.-A.
