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: o S-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-plementary-symmetry amplifiers bine excellent performance with economy. S 150 1,2, ~ l< ~ 100 o 25 50 7S 100 125 ISO 175 zoo EFFECTIVE CASE TEMP. OR CASE TEMP.
