150 Watt OCL Power Amplifier
If you are fanatical about the use of transistors jengkol 2N3055 and MJ2955 then this circuit is
the answer. This OCL
power amplifier circuit deliver a blasting 150 watt to a 4 Ohm
speaker. The amplifier circuit is very cheapest and can be powered from 24 to 32 V/5A dual power supply. You must
try this
circuit. Its working great. Because Transisitor on the final amplifier
will be very hot then add the aluminum finned cooler and the fan so that
the transistor is not too high temperatures
- Use a well regulated and filtered power supply.
- Connect a 50K POT in series with the input as volume control if you need.Not shown in circuit diagram
The
transistor 2N3055 NPN and MJ2955 PNP are a silicon Epitaxial-Base
Planar transistor mounted in Jedec TO-3 metal case. It is intended for
power switching circuits, series and shunt regulators, output stages and
high fidelity amplifiers.
