   Someone suggested disconnecting the resistor in the headphone jack.  This
may be OK, and may be quite dangerous.  Some amps NEED a termination in order
to be "happy".  The resistor is to assure the amp of this.  When the headphone
connects, it either disconnects the resistor, or parallels it.  The resistor is
usually of a higher impedance than the headphones (being 8 ohms) and therefore
effectively disappears.
