Power Amplifier 2000 Watt

This is linear power amplifier 2000 Watt which need advance knowledge in electronics since the schematic diagram is very complex for hand made circuit. I think you have to re-design the schematic diagram using circuit diagram software designer such as diptrace, eagle, expresspcb ect. Or just order the PCB online, they will be glad to make the PCB for you.

This kind of power amplifier circuit need high power consumption, so you need to build the power supply carefully. It need dual polarity power supply (+85, 0, -85) and of course with high DC current of about 20A.

Just need to think again if you want to build this kind of power amplifier 2000 Watt.

Here the circuit diagram of 50W power amplifier. The amplifier uses a pair of power transistors that are MJ2955 and 2N3055 to amplify the input signal. You must use a heatsink on those transistors. The below design diagram uses for single input/output channel, just built two similar circuit to make it dual channel (stereo).

PCB layout:

Power Supply Circuit:

This amplifier require dual polarity output power supply (+, ground and -). Use this power supply circuit:

Transformer: 3-5 Ampere, 24V secondary output
Diode: Diode bridge 5A or 4 piece of single diode 5A
