Can someone tell me what, typically, is the voltage output from a
headphone jack on a home stereo? If I have some voltage coming through
the jack, is that the power to the headphones/speakers or could it be a
leakthrough from the power supply of the stereo itself? I does seem to
vary with volume. Thanks.

there should be no dc voltage at the headset. the ac voltage will vary with the
volume and should be typically less than 1 volt. check for voltage with no
signal output to see if there is a problem.
