In case if the link to schematic of Power Amp disappears, I included the circuit diagram at the end of this video divided into four parts - for greater detail and image resolution. - วิทยาศาสตร์และเทคโนโลยี
What an absolute Legend you are, not only did you post all the details for the parts and scenatics in the comments, but you even follow it up with this. I dropped my moms amp today and one of these resistors got pierced.
You saved me so much time. Thank you a lot!
thanks for posting m8 i am still waiting for the last parts hope it works. glad I replaced the fans as well one of them was running very slow when I bench-tested it
