OCL power amplifier circuit used in the circuit above is the type of power amplifier OCL (Output Capacitor Less) with a power output of 70 Watt. Circuit 70 Watt power amplifier OCL is working on a class AB with symmetrical voltage source of VCC ± 25 volts DC to ± 32 volts DC. OCL power amplifier circuit uses a 70 watt power transistor complementary transistor TIP in 2955 and TIP 3055. 70 watt power amplifier in the circuit can be used to drive the load (4-16 Ohm loudspeaker). Power supply circuit power amplifier can use power supply circuit with current 5A symmetrical. For stereo audio system needs to make a power amplifier OCL circuit tone control + over 2 units.
