Thanks for the answer. So how to repair this subwoofer? I don't want to make mistakes. The most pressing problems at the moment are: What are the names of the diodes D 2 and D 3 located there? There are no markings there. Specifically, it is about diodes (semiconductor diodes?) with only D2 and D3 written next to them. It's only about the NAME of these diodes, because there is no such name there.

Hello. I am looking for a service manual for the Klipsch SW 112 subwoofer. Best Regards SK
