Driver circuit for transistor amplifier

Driver circuit for transistor amplifier

This is the driver circuit for transistor amplifier. this circuit can be used with PNP and NPN transistors. we can use 2sc5200 and 2sa1943. we can use 30-0-30 voltage to 80-0-80 voltage. 

The circuit diagram is here

2sc5200 Polarity is NPN. Max Collector Power Dissipation is 150 Watts. The Max Collector-Base Voltage is 250 Voltage. Max Collector-Emitter Voltage is 250 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 17 amperes. 

2sa1943 Polarity is PNP. The Maximum Collector Power Dissipation is 150 Watts. The Maximum Collector-Base Voltage is 250 Volts. The Maximum Collector-Emitter Voltage is 250 Volts. The Maximum Emitter-Base Voltage is 5 Volts. The Maximum Collector Current is 17 amperes. 

This circuit doesn’t have speaker protection. here, we need a speaker protection circuit. here is the link to get the speaker protection circuit. Diagram is here

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.
