    A small project headphone amplifier comes with a 16 volt plug size power supply

    Will I do "much" damage using a 19 volts power supply I ask because I have a spare laptop power supply like the one below.

    Just stick in a series resistor (with possibly a capacitor) ot drop the voltage. Calculate the resistor required based on current draw.

    ...just be aware that the volt drop will vary with current draw though - dunno how constant the current drain of the amp might be though. Or you could use a LM317 adjustable regulator anda couple of resitors, but for the hassle it'd be easier to get a new PSU.
    Can\'t think of anything suitably humourous or interesting. I\'ll have a think and then copy someone elses.

    Sure, that's why the cap's there to help smooth it out. It will most likely be fine.... Good enough for government work (and Dave )
