Build a Simple 10 Watt Power Amplifier Wiring diagram Schematic
The aim of the project was to make an audio amplifier that can deliver up to 10W R.M.S. power output.
Risk of instability if no input connected. When testing, connect R (about 3k3).
Needs well smoothed power supply of about 20 to 30 volts. Peak power is well over 10 Watts.
The table below shows the approximate voltages to be expected when using a 24v supply and with the variable resistor set to give a current of about 40mA in the output stage.
