Power Amplifier Transistor Amplifier. The four transistors in parallel will increas the maximum current output capability by four times compared to a single transistor. The transformer is the main and important subject for making a good quality amplifier.
We used 2sa1943 and 2sc5200 transistors. A power transistor differs from the other transistors in the following factors. A very simple and easy to build class ab audio amplifier using four transistors is shown here.
We can see where we used a 45 0 45 voltage and 15 ampere transformer.
It is a transistor amplifier. We used 2sa1943 and 2sc5200 transistors. 32 992 mwt 173 is a low power mesfet designed to be an lna low noise amplifier. Then the audio signal coupling to through the c1 and r1 to amplifies by transistor q1.
