Which TPA3116 is this?

[WASTd]

Recently my old TPA3116 gave up and I wasn't able to fix it, so I bought a new one but unfortunately theres an audible hiss and a pop on turn on. So I wanted to do the gain mod but I also stumbled across that I might also need to change the input capacitors if I change the gain. I'm not very informed as you can tell so I got couple questions if you could help.

• Is there a common name for this board so I could search around for mods for it?
• Could someone point at where the input capacitor should be? Should I actually change it if I change the gain?
• Where are the Master and Slave gain resistors?
• Should I change the 50K pot?

Thank you!

@zek It is indeed haha, thats the exact board I bought, I was just wondering if there was a specific name for it so I could maybe look for mods specific for this board.

Maybe you should try the model number WM-034GT. 🤫

You may be able to swap the bad chip on the old board.
