The Driver Stage of an amplifier provides the proper current to amplify the audio signals using the output power stage of the amplifier. The heart of an amplifier is the driver section, and it will decide the quality and power of the audio output through the power stage of the amplifier.
Most of the Power Amplifiers need this Driver Stage to work amplifiers properly. In most conditions the driver section of the amplifier gets damaged, in this post, I would like to share the 1000-watt amplifier driver stage circuit and its components list.
1000 W Driver Amplifier Circuit
Components Required
| Component | Value | Quantity |
|---|---|---|
| Transistor | 2SC5200,2SA1943,TIP41, TIP42, C2383 | 1, 1, 2, 2, 3 |
| Capacitor | 4.7uf, 220pf, 100uf, 100pf, | 1, 1, 1, 3 |
| Resistor | 47K, 560R, 1K, 3k3/1W, 100R/1W, 56R/2w | 4, 3, 1, 2, 2, 2 |
| Liner pot | 1K | 1 |
| Diode | 1N4007 | 2 |
| Power supply | 80-0-80 v DC dual power supply | 1 |
The driver section is working in 80v dual power supply DC voltage. The circuit is constructed with more high-quality transistors with high current carrying capacity. The audio input is fed to the 4.7uf electrolytic capacitor. The C2383 is an NPN transistor which pre amplifying the input signal and feeds to the other power transistor section.
The Output section of this circuit contains the SP, B+, and B- the B+ and B- are the connecting contacts for the power stage of the amplifier. The power stage contains a lot of power transistors and the base of the transistor is connected. SP is the feedback connection.
