scheme power amplifier 20W RADIO
scheme 20W power amplifier (AUTO BOOSTER FOR CAR-MOTORCYCLE 20 WATTS)
The assembly described offers a boost of 20 watts that will allow you to realize a power amplifier with which one can increase the output power of a car radio up to 20 Watts maximum.
The input IN is connected to the output of the car radio, output U is connected to the speaker as Represents the scheme.
It is very important to ensure that the speaker has no connection to the chassis ( mass) ; otherwise, integrated circuit IC1, a TDA 2004 would be instantly destroyed.For mounting of components, carefully monitor implementation of the scheme composanls. The alimenlalion will continue at 12 Volts.
LIST OF ELECTRONIC COMPONENTS: All resistors are of 1/4 watt unless statedotherwise. R = 100 Ohms R2 = l, 5Kohms R3 = 180 Ohm R4 = 470 Ohms R5 = 10hmR6 = 10hm Cl = 0, lpFpol. C2 = 1000pFceramique . C3-10uF16Velec. C4 = 0, luFpol.C5 = 0,22uFpol. C6 = 0,22yFpol. C7-0,22uFpol. IC1 = TDA2004 1 Heatsink
