If the headphones are plugged in, the circuit to the usual speakers would be held 'open' by the headphone stereo jack and nothing will get around that, --if-- it's hardware. If you plug the headphones in and had the speakers working too, then the load would be what? 4 ohms? instead of 8? One of the hams can do the math for ya, but it wouldn't be good to do that to the amp, as I seem to dimly recall from electronics 101 taken 35 years ago. DC parallel circuit. E= I times R, so reducing the resistance increases the amperage proportionately. Little teeny tiny transistor possibly goes <poof!> after it has time to warm up enough. Am I right so far? Some one with some brains left over, please pass them to me. <g> Ric
