well, I have reinstalled everything from the factory, and I have done a test. instead of the 2sc2078 I have placed a good 2sc1969.

The final power has been 3.8w again.

Either a component or setting fails before 2sc2314, or something discharges power to ground after 2sc1969.

I comment on this detail in case someone intuits what it could be. I think that the original problem was not the final transistor, but that there is another fault component, or bad potentiometer adjustment.
