If you look at my circuit you'll see that when the PIR relay open, pin2 of NE555 will go low. This will then trigger the NE555 and the output will go high.
My problem isn't in this part of the circuit, but it's on the output stage of the NE555. When i test the circuit with an LED everything is working fine, but the moment i connect my amplifier and alarm sounder to the output, Q3 blows.
There's nothing wrong with my amplifier because when i connect it straight to the power supply, it's working correctly. The current the amplifier and alarm use is about 1,35Amp
Can you please tell me what the problem might be on the output stage of the circuit
