Symmetrical power supply circuit 12v input voltage +350 V-350V integrated sg3525 used to control the PWM turns. Author Lamp amp is designed to run 350volt 400mA per channel output power, in addition to strong oladıkc +15 v and 78xx series regulator depending on downs.
Dc to dc inverter circuit SMPS (switched mode power supply) works as a lamp to my mind first, but the auto amp amp jolt in the car, etc. How to use the car going. I do not know what happens. Circuit of the circuit diagram, pcb diagram ETD49 transformer windings have the information.

100W Amplifier Circuit TDA7293
TDA7293, despite the small performance too high an amplifier integrated manufacturers (ST Microelectronics) “120volt 100watt DMOs audio amplifier with mute st-by,” says symmetric +-60V 120-volt dc able to work with TDA7293 datasheet information according to the maximum recommended working voltj the +-50v 60V input audio signal when it is not in the lowest operating voltage +-12V have. Circuit diagram of the PCB drawing and material list.
Earlier TDA7293 DMOS audio amplifier 100w amplifier integrated circuits made with the same count was shared with the others, but this circuit TDA7293 PCB design was quite small and tidy. TDA7293 amplifier circuit 100W DC filter capacitors in printed circuit there should be added in addition to the diode bridge
