"It's no longer junk". Haha, that's a matter of opinion! Having said that, it was worth the $2 that you paid in entertainment value for us viewers. Thanks for showing us the diagnosis and repair. I have one of these modules that is destined for a small guitar practice amp. I hope I got a good one.
It is supposed to be14 watts but that is peak to peak so 1/2 of 14=7 times .616 or average gives you 4 watts. It is enough to drive a mid sized speaker pretty well.

Lol. For some reason I misplaced this thing. No idea where it got off to.
David, great little project my kind a guy!!! Big thumbs up!!
Thanks. Waste not want not.
Hey dude , can I use a function generator at the audio input that has a max voltage output of 3 volts , for this circuit ?
Oh my yes. You shouldn't need near that much. It should be fine at .5V or less. 3V should drive it into near distortion.
I have swapped the resistors and now there is too low audio at output.
All I can say is check the rest of the parts. Don't trust them to do anything right. Good luck.
What is the diode value and specifications?
The diode is just a 1N4007 rectifier diode. .6V drop.
Nice video, how many watts is the output?
