They are especially characterized for use as output devices in. audio applications, and are provided in the JEDEC TO-3 package. ·The 40-watt audio· amj:ilifiers shown iri ·Figs: oS-ana· 6 use RCA1B07 and RCA 1BOB transistors as output devices in ·conjunction with nine TO-39 discrete transistors, and ten· diodes_ The amplifier shown in Fig. 5 uses a 64-volt split power supply with the output directly coupled to an B-ohm speaker. Fig. 6 shows an amplifier with a 5B-volt·split supply with the output directly coupled to a 4-ohm speaker. These 40-watt Darlington full-complementary-symmetry amplifiers combine excellent performance with ...
