Thank you for your prompt response a while ago I am trying to repair it but the lack of information has stopped me in the identification of some components. Here I show you some photos of the amplifierView attachment 7136View attachment 7138 These are diodes that, due to their housing nomenclature, I cannot identify.
It is best to acquire a schematic diagram. If the amplifier is from LD systems then you can contact Adam Hall in Germany and ask for a schematic diagram. You will have to sign a declaration that you will not share the schematics due to copyright reasons.
I had a repair once on a similar amplifier but not the same as yours and I got a schematic from him.
The mail address is email@example.com
If you need to verify the smd components then you can search on line for the smd code book. You will probably find what you need to know.
Try also here maybe you can get a schematic

Silvio at first option didn't work for me either. I failed to establish communication. Regards
This amplifier model uses the IR2156 + totempole as a pwm. When I checked it it had damage in the whole hot part since they insisted a lot to turn it on, aggravating the situation of the machine. Now I don't know what to do with so little information about it
