Audio power amplfier

Power Amplifier Circuit with 2n3055. Simple and low cost power amplifier. The optimal accumulation voltage is about 50V, but this amp assignment from 30 to 60V. The acute ascribe voltage is about 0.8 – 1V. As you can see, in this architecture the apparatus accept a big tolerance, so you can body it about of [...]

Here is another mini circuit project. You can comment here if get something wrong with this electronic schematic design

A high gain transistor like the MPSA-18 for the first transistor will allow a much larger value for R, up to 1 Megohm. The circuit should draw between 18 and 45 mA, a value determined by the transistor gain and the value of R.

Here is a phase-shift audio oscillator with excellent distortion characteristics thanks to “softened” diode limiting provided by the 1N914 and resistor divider and degenerated gain provided by the 68 ohm emitter resistor.
