Electronics Help Care Amplifier circuit diagram
This is a mini amplifier circuit diagram. It’s so easy to make. This amplifier for the learning people. It’s a DIY project. Here we can use a maximum 18-0-18 voltage. Here needs dual voltage. 12-0-12 to 18-018 voltage can be used. 30 watts output.
How to add an extra transistor:
How to add an extra transistor? A Maximum transistor amplifier can add extra transistors, but it will not work if we don’t increase the amperes or voltage. If we want to add an extra transistor, then we have to increase the voltage and amperage. like the voltage is 35-0-35 and 3 amperes for 2 transistors. If we add an extra 4 transistors, then we have to add an extra 4 amperes. And the voltage can be 45-0-45 maximum.
Every amplifier needs a speaker protection circuit. This circuit also needs a speaker protection circuit to protect the speaker. If any cause the circuit to burn, then the voltage can’t burn the speakers.
We can get many amplifier circuit diagrams. This circuit can be used in a 2.1 sound box. We can make a subwoofer amplifier using this diagram. To make a subwoofer, we need a low-pass filter circuit. To get the lowpass filter circuit, please visit here LOWPASS FILTER. We need this low-pass filter to make a bass amplifier for 2.1 audio. This low-pass filter makes the sound only bass. It’s also a pre-amplifier. We can use this circuit in any amplifier to make a subwoofer amplifier.
