Power Amplifier 2n3055 Circuit Diagram Schematic

Power Amplifier 2n3055 Circuit Diagram Schematic

Simple and low cost. The optimal accession voltage is about 50V, but this amp appointment from 30 to 60V. The astute accredit voltage is about 0.8 – 1V. As you can see, in this architectonics the accoutrement acquire a big tolerance, so you can anatomy it about of the components, which you accretion at home. The and transistors can be any NPN acquaint adeptness transistor, but do not use Darlington types… The accomplishment adeptness is about 60W.

Descriptions:

- capacitor C1 regulates the low frequencies (bass), as the capacitance grows, the low frequncies are accepting louder.

- capacitor C2 regulates the academy frequencies (treble), as the capacitance grows, the academy frequencies are accepting quiter.

- this is a chichi B amplifier, this means, that a accustomed allegation breeze through the end transistors, akin if there is no arresting on the input. This accustomed can be acclimatized with the 500Ω trimmer resistor. As this accustomed incrases, the complete of the amplifier gets better, but the end transistors are added heating. But if this accustomed decrases, the transistors are not heating so much
