It was very helpful. In another video, there was a tone control board attached to the XH-A150. It involves removing the chip resistor and soldering a wire of tone control board to it. In your video, you cut the board pattern, but how about removing the chip resistor?

Ow yeah thanks for asking me my friend, The resistor is very important to decrease the excessive signal from Bluetooth audio receiver to amplifier. And If I remove the resistor for wire connectors instead of cutting the terminal. The SMD resistor is very sensitive and prone to heat damage if I solder it into potentiometer output. So the best way is cutting the terminal and I recommend to put a glue to protect the solded wire from twisting to prevent terminal damage. 😊

@@Segantech I haven't been able to get a portion meter yet. I would like to decide what to do based on your advice. There is a bit of resistance when cutting the pattern. thank you.

@@SegantechI got portion meter, and tried the method of removing the chip resistor, but but no good results were obtained. Then went your way. This one went well. What you said was correct. But Soldering to the board was difficult for me. By the way, the portion meter was set to 100KΩ. Thank you very match.
