ach lOOmA, can replace the battery to power transistor radios. London using B power amplifier circuit, the load current varies greatly with the volume, if such a power supply voltage variation is relatively large, this work is detrimental to the radio. Therefore, the circuit is set resistance Rz, in the no-load power, it also consumes a certain current, the load current fluctuation when output voltage is still relatively stable j resistance R, is to improve the filtering effect of reducing hum and set up. S2 is provided for the conversion of the output voltage.
