Yes, Thank you op. I have a similar problem with the same speakers. The left channel stopped working and upon a little investigating, it seems, that the Q10 output transistor is physically broken. I'm not sure what might have caused this. Nothing looks burnt. I still have to remove the HF board. If anyone can help, i would appreciate it. I will take pics when i remove the board. I'm not sure if i should start a new thread or post here ? Maybe someone could comment on that too. Thanks

Please do not hijack other thread, you have your own thread now.

If you want a better answer then you should attach some clearly photos for your amplifier, it will be help for experts to help you.

 

That post was to thank the op for the info he provided. Maybe something got lost in translation.? thanks
