And connect the power supply module to the transformer. This is how to connect the amplifier module to the speaker, power supply and audio input.
for Features DC Current Gain hFE 2070 IC 4 Adc CollectorEmitter Saturation Voltage VCE(sat) 1. Transformer for the mono amplifier should be 35 + 35 volts AC with a minimum of 3 amps. 2N3055(NPN), MJ2955(PNP) Preferred Device Complementary Silicon Power Transistors Complementary silicon power transistors are designed generalpurpose switching and amplifier applications.Power Supply Circuit for 120W Power Amplifier Use mica between the transistor and the heatsink. The points are: prevent circuit shortage, use proper isolator and use thermal compound for maximum heat spreading to the heatsink. How to mount the transistors to the aluminium heatsink, see below image: potentiometer of 20K if you want to add volume control.Zener diodes between 20 and 24 volts : 1.10 Ω to (1W) – brown, black, black : 1.
