Silicon Transistors for 40-Watt full-Complementary-Symmetry Audio Amplifiers
JEDEC TO·220AB
H·1535R1
RCA1C07 and RCA1COB are n-p-n and p-n-p epitaxial-base silicon power transistors, respectively, especially suitable for audio-output applications_ These devices are provided in the economical JEDEC TO-220AB version of the VERSAWATT package_
The 40-watt amplifier shown in Figs. 1 and 2 uses the
RCA1C07 and RCA 1COB in conjunction with seven TO-39 transistors, ten diodes, and a 64-volt split power supply_ The amplifier output is directly coupled to an B-ohm speaker_ The high-frequency performance of this 40-watt amplifier will provide excellent reproduction for the most critical listener.
