Amplifier circuit using STK035:

This is an amplifier circuit using STK035. This diagram can produce a 35W+35W output with an 8-ohm load. It’s a stereo audio circuit diagram. The voltage should be a minimum of 25-0-25 and a maximum of 70-0-70. Dual IC for dual side.

Stk4231 Circuit Diagram:

This is the Stk4231 Circuit Diagram. This is a 100Watts+100Watts amplifier. This Stk IC can make 200 Watts. We can use a maximum 50-0-50 voltage. It’s a stereo audio amplifier.

Transistor amplifier circuit diagram using high and low voltage:

This is a Transistor amplifier circuit diagram using high and low voltage. This amplifier runs on dual voltage. positive 50 volt, positive 100 volt. and negative 50 volt, negative 100 volt. Here, use a MOSFET to run the high voltage. Here, use two transistors. This pair of transistors makes 300 watts. 2sc2922 and 2sa1216

Transistor amplifier circuit diagram using high and low voltage

This is the Speaker protection circuit diagram. It can protect our Speaker from the 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 direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
