This small audio amplifier circuit in complementary symmetry was found in the 1974 Mullard Databook. The output pair can also be the BD135 and 136.
We found this circuit in an 80's Electronic Design. The circuit uses an integrated of the time....
With this circuit (shield) we can control a load from 500 mA to 1 A, depending on the transistor, using a...
The consumption of this circuit is only 50 uA in the standby condition and 4.5 mA when supplying a pulse...
