Class A Audio Amplifier Circuit Diagram. You can power up the speaker and audio amplifier using a 12v battery a solar panel lithium ion cells 110 220vac to 12vdc adaptor. This experimental 3 transistor class a audio power amplifier delivers 25mw into an 8ω load or 50mw into.

The output of this small amplifier in which a 6v6gt output pentode is connected as triode is about 4 5 watts. This is the circuit diagram of 24 watt class a linear audio amplifier built and tested by marc klynhans from south africa. The circuit diagram for tip35c audio power amplifier is shown below.

A transistor acts as an amplifier by amplifying the input signal.

This is my first successful vacuum tube project. The circuit diagram for tip35c audio power amplifier is shown below. Anyways do you know have a lot of circuits about audio or amplifier. This is my first successful vacuum tube project.
