Transistor Amplifier (CB218E)

This is a traditional complementary-output transistor amplifier sourcing 2 to 4 watts to a 4 ohm load when powered from a 9 V supply. The current is up to 500 mA and P2 must be adjusted for 50 mA current drain without input signal. The output transistor must be mounted on heatsinks. The circuit can be used in intercom, experimental receivers and other applications.
