The phase inverter circuit runs from Terminal 3 of the output transformer to the cathode of V-3, the other leg of that circuit being the amplifier ground connections. V-4 is the phase inverter tube, corresponding in function to V-2 of Fig. 201 (page 513). The loudspeaker crossover network (pages 436-437) is shown to the right of the output transformer. The rectifier unit at lower right provides d.c. for the loudspeaker field coils (see Chapter XXII).
