Find Mp3 Player Spares and Mp3 Player Parts

I ordered some of these leads, as I really needed ones with a 3.5mm plug which had a small overall body diameter: I do a lot of PA work, and I'm sometimes asked to play specific songs from somebody's phone. (A real pain, I know!) Standard sized plugs often won't fit through the hole in the phone case. I was surprised to see that the Left and Right cores of the cable had been soldered together (to pin 2 of the XLR). To prevent loading on the source outputs (as well as reducing any crossfeed between channels), it is normal practice to have small value resistors in series with each signal: 470 ohm is common. The junction between the resistors is connected to the XLR pin 2; a 20K resistor is also connected between this junction, and pin 3 of the XLR. Pin 1 is still connected to the sleeve of the 3.5mm plug. All resistors should be 1%, you'll need 1/8 watt ones to get them to fit into the XLR. So, I going to have to modify these.....
