This circuit provides a few watts of output and can be used in the car as an auxiliary amplifier. Transistors must be mounted on heatsinks and the speaker can be 4 ohms or 8 ohms.
The two circuits we suggest are from the book Optoeletronics - Theory and Practice by Texas...
The presented rectangular oscillator makes use of one of the four NAND ports of a 4093 integrated...
This circuit can receive the signals from CIR10466 or another like this, of the many described on this...
