Electronics projects 2n3773 2sc5200 amplifier circuit 150w audio amplifier circuits transistor amplifier date 2019 08 04 for a long time i was going to share with you the materials on assembling a transistor amplifier with unipolar power assembled in retro topology which is still of interest to some radio amateurs. Amplifiers ranging from 50 micro watts 75 watts output.

The single stage common emitter amplifier circuit shown above uses what is commonly called voltage divider biasing. T22 and t23 take current measurements over 0 47 ohm resistor and take the t11 and t12 to the cut and go to protection. You can choose 0 5w to 1 200w.

This device can also be used in power switching circuits such as relay or solenoid drivers dc dc converters or inverters.

This type of biasing arrangement uses two resistors as a potential divider network across the supply with their center point supplying the required base bias voltage to the transistor. A challenging but high quality design. T22 and t23 take current measurements over 0 47 ohm resistor and take the t11 and t12 to the cut and go to protection. For amplifiers to operate properly they must be correctly biased.
