Hello!
I can't have the Boost mode functionnal. When it's on, the volume is getting really low.
I've checked the voltage on all J201. It seems fine, to me. If somebody can confirm.
I'm trying to follow the boost stream but it's a bit tricky. From the schematic, can someone confirm that enabling SW2 leads to use the IN2 section ?
So I had to check R17, C14 and so on.
