Default Support to repair Rockford Fosgate 1501bd amplifier

Hi, I have this time I got broken after changing several output transistors (IRF3415 and IRF6215) to connect, turn on the LED protection and noted that heating the Q115 (IRF337) I check voltages and appears to be correct in several points of the plate (HV + and HV-134V) any idea?

Do you mean Q15?

That's supposed to be an LM317, not an LM337.
