Audio Amplifier Protection Circuit. D Mohankumar. Now you can protect your HiFi amplifier from damage due to excess heat. This circuit will cut off the power to the amplifier board at the moment it senses a high temperature. It automatically connects power when the temperature returns to normal. The circuit uses an NTC Thermister as heat sensor ...

Shown here as a single transistor, Q2 is normally a darlington or cfp. There are two small problems with this circuit, one is that supply line noise is injected into the circuit via R1, and also the protection transistor is already biased on slightly even with no amplifier output voltage or current, with as much as 300mV base-emitter voltage.
