1600W Power Amplifier Class-G PCB Layout

The following is a PCB layout for a G-class power amplifier, previously here is a little explanation about class G power amplifiers, namely Class G classified as an analog amplifier which aims to improve the efficiency of B / AB class amplifiers. In class B / AB, the supply voltage is only one pair which is often denoted as + VCC and –VEE for example + 12V and –12V (or written with +/- 12volt). In class G amplifier, the supply voltage is made multilevel. Especially for applications that require high voltage power, so that the supply voltage is efficient, there are 2 or 3 different pairs. For example, there is a supply voltage of +/- 70 volts, +/- 50 volts and +/- 20 volts. The concept of class G Power Amplifier circuit as shown in figure 1-30. For example, for soft and low sound strings, the active pair is a supply voltage of +/- 20 volts. Then if needed to drive loud sound, the supply voltage can be switched to a maximum supply voltage of +/- 70 volts.

And here is a PCB Layout power amplifier 1600W Class-G Amp, you can also create or print this PCB yourself by downloading the Layout file in the form of a PDF file. End of posting.

This Class G power amplifier can be supplied voltage up to 120VDC Symmetrical and at least 42VDC symmetrical. This power amplifier can produce power up to 1600W RMS on an 8 Ohm Load with a good and maximum power supply voltage to control this amplifier. In addition to the final transistor, it is also very influential, you can use the original Toshiba 2SC5200 / 2SA1943 or NJW0302 / NJW0281G transistors in order to get quality and maximum results.


Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.

Boa tarde, tem como disponibilizar o arquivo completo?

Can i use 2ohms loudspeaker in class G amp.

How much power it can deliver in 4 ohms ?

This Post have'nt any importance why you put it here ?...pcb not clean & no schematic...thanks !!!!

circuit size how much, thansk you

circuit size how much, thansk you

in the stepper there is an empty pin, what is that for? at the foot of the resistor 47k 0.5w
