The power amplifier circuit of this be regarded as highly popular In producer stereo readymade group that have both of amplifier radio tape plaything and tuner include in same group. This IC group produce from a factory sanyo have elect but beside vacate 7 watt go to until 20 watt RMS be , STK435 = 7W+7W (27Volt supply) , STK437 = 10W+10W (33V) , STK439 = 15W+15W (39V) , STK441 = 20W+20W (44V) , STK443 = 25W+25W (49V).

If you take an interest to build this project as a result may assemble the equipment follows the circuit. By use IC every the number uses the circuit and PCB the alike. Except level Voltage that differently thus. the capacitors at use in the circuit especially electrolytic. should use model durability voltage the just right. Because of this circuit be model readymade half from a factory. When build finished then don’t have to fining decorates the circuit anyhow call that. if build not wrong also the work has immediately.
