PCB for the project from DIY Perks video:

Need to be tested, but this is basically an orderable board.
As the parts are THT, I didn't use any particular manufacturers parts so you could buy locally or order from where you would buy the THAT1512 chip and the 15V PSU.
THAT1512 replacement parts:
THAT1510
INA217
INA163
SSM2019
SSM2017
P.S. The preview here seems to be in the past, if you open the project in EasyEDA, the design is as in the thumbnail. Hopefully this updates soon.
