This circuit is from Motorola's 1990 Linear Databook. The transistors allow equivalents and the output power depends on the supply voltage. The power supply must be 30 V symmetrical.
This circuit was obtained from an American documentation from 1969. The operational amplifier and...
This circuit has very high input impedance and a differential input. The gain is 1,000 and the...
This high-power circuit excites capacitive loads and can be powered by voltages from 14 to 32 V....
