12 Volt amplifier push-pull using 2sa1943 transistor:
This is a 12 Volt amplifier push-pull using 2sa1943 transistor. This amplifier can produce 60 watts using 12 voltage. 3 transistors were used, one for input and the other 2 for output. and 2 transformers. one for the input transformer and another for the output transformer.
This is the Speaker protection circuit diagram. It can protect our Speaker from burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow any direct voltage to be sent to the speaker. This circuit is very important for protecting the speaker.
