JEOECTO- 3
Silicon Transistor for 120-Watt Quasi-plementary-Symmetry Audio Amplifiers with Parallel Output Transistors
H- 1570
RCA 1804 is an n- p- n silicon pi-nu transistor in a JEDEC TO-3 package. This device is especially characterized for audio applications, and can be driven by RCA1Cl.2 and RCA1C13 transistors.
The 120-watt amplifier circuit in Figs. 1 and 5 uses the RCA1804 in conjunction with eleven other discrete transistors, twelve diodes, and a 130-volt split- power supply. The amplifier output is directly coupled to an B-ohm speaker. This RCA 120-watt audio amplifier is especially designed for top-of-theline quadrasonic use in applic~tions requiring %k W of quadrasonic sound with excellent tonal quality.
