BMW Philips Amplifier 65.12-8 352 296 Made In Germany

[Music] now we can see in detail the big board power on common circuits and some on the other connections that we previously described the 12 volts goes to rectifiers u 1 and 2 then the 12 volts goes to u 3 an N MOSFET and channel MOSFET use it as a switch when the gate of you tree goes too high you tree acts like a closet switch and let the 12 volts to supply the power transistor section the control circuit of the power transistors and the board to he derp entry and 28 new tree gate is controlled by a circuit represented in the schematic the command from the small board arriving on either pin 30 shorts it to ground then it powers the section with the operational amplifiers and at the end it also put in conduction you tree letting the power transistors section to be supplied with also the other sections the comment from small board either pin 30 also arrives on this part of the circuit
