Hi @R!f@@,
Excellent fault finding information! I have the exact same one with very similar failure in NZ. In my case one of the MOSFTS in the PFC stage & the 6.3A fuse also were damaged. I haven’t been able to identify the small 8 pin IC on the daughter pcb. Would you be able to help please?
Thank you in advance!

Sure.
But I may reply late. I am quite busy these days.
I haven't been able to test the repaired PSU in the speaker as of yet.
Post some pics. We'll go on from there.

 

By the way, does your board shows the low shunt values.
I really need to know tht.


If this area is clear on your PCB pls show me.
