MJE2955 (PNP) and MJE3055 (NPN) can also be used instead. Larger heatsink provides a better result. This circuit available in kit. Not to mention, the Heatsink connected with the tab also get the same connection. In sound electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load. The first stage of the amplifier is based on T1. Speaker impedance can be best understood using the relation between water flow inside a Pipe. Input capacitor 470nF is the DC blocking capacitor which will only allow the AC signal to pass. Any temperature increase in the final stage leads to an increase in the current which leads to a further increase in temperature. But for this tutorial, we will build a 40W power amplifier which will drive an 4 Ohms impedance speaker. The oscilloscope is connected across the output against 4 ohms load on channel A (Yellow) and the input signal connected across channel B (Blue). This is the circuit diagram of stereo pre-amp with volume and tone control. We can see the output difference between the input signal and the amplified output in the video:-. Also, in some cases, where tone control is needed, the tone control circuitry is added before Power Amplifier.
