Let’s start assembling the amplifier PCB first, so we can have it ready later when we assemble everything. Download my GERBERs files from below for free. Then go to PCBWAY.com and click the quote now button. As always add the settings such as the PCB size, amount and color. In my case I want my PCB to be red. Save to cart and on the next page upload my GERBER files. Make the payment and in just a few days, receive the awesome PCBs for the amplifier. They look so nice so we could assemble it. The component list is quite specific and you need to use good quality capacitors. So make sure you get some non polarized audio capacitors like in the part list above. They are a bit more expensive but we really need them. Connect all components and check the final schematic for all the values. Now I have the PCB all assembled.
