over here you may see some pictures from the debugging and measuring "as was" procedure ...notice that the boards UT was the old boards while now days Smart kit provides a better pcb with a few mistakes corrected

The biggest problem of the amp was the flat cable given inside the kit to wire the board with the outputs that actually was a huge inductor or capacitor between the BCE of the N and the "P" transistor "P"= lower npn
this is all I see.
