Click to expand... output power devices, the components that set up their bias and possibly the driver stage before the output. In any old audio amp, assume the electrolytic caps need replacing. They have very short lives and fail often. If it has a switcher power supply, one or both sides may have blown. Test the power supply rails first. Last edited: Jun 26, 2012
