Hi everyone I am trying to troubleshoot a ppi900.4 that has very low volume on the rear output sections. The gain is all the way up and the speakers are very quiet. The front section of the amp is good no problems there.
I opened the amp and checked with an oscilloscope every transistor and there are 6 T460 I imagine this is the output section. They all had the same square wave.
What should you look for if all the transistors that have to do with the output section are working at the same voltage ???
thank you !!

Post a photo of the component side of the main board and the component side of any driver boards if no one can help.
