DiY High Power Amplifier EEEngine G77 3000W

 Hello Guys, this time Elcircuit will share the PCB layout of the EEEngine G77 amplifier, designed by Mr. Kartino Surodipo and laid out by WER.The following is the PCB layout for the G77 amplifier:

This amplifier can be supplied with a minimum voltage of +90V 0 -90V up to +180V 0 -180V

The power that can be generated can reach 3000W with a load of 4 ohms at a supply voltage of +180V 0 -180V DC.

The heatsink used is 3U 30cm wide 9.75cm

If you are interested in making it, you can download the following gerber file:

Gerber File EEEngine G77 3U 30cm

How to print PCB at JLCPCB can follow this step.

First, visit the JLCPCB site. then log in or register first (if you don't have an account) the button is in the top right corner click "Order Now"

Then click  "Add Gerber file"

Select the Gerber file that has been downloaded at the end of the post link, but before using the downloaded file, the file with the name "Full UcD 2K mr.kartino (extract first)" must be extracted first.

The file already contains schematic same as PCB marking, BoM files, and PCB Layout gerber, for Gerber there are three, 1 for amplifier board, and 2 buffer versions.

Then select Gerber one by one, then double click. Wait for the upload process to complete.

Then select Gerber one by one, then double click. Wait for the upload process to complete. then if you want to add another Gerber file, just click "Add Gerber file" again. if the three PCBs have been uploaded and you have selected the option for each PCB,  click the basket,  go to payment by clicking (Secure Checkout), and complete the payment on the next page. Payment can use a credit card, or debit visa, and also PayPal.
