Matt;
If you want to supply 2 volts to the tube filaments then the white/black wire is what you want to use, it's not that used the brown wire would hurt anything but the resistor in series would drop the 2 volts down at least 1/2 a volt. The sets I have don't have alternative leads for the A+, what they have is a set of screw terminals, where you jump out the resistor for powering the filaments off of a wet cell, and remove the jumper wire when using an Aircell. Since you cannot buy Eveready Aircells anymore the dropping resistor, does not really have a purpose, I've always operated farm battery radios off of an AC powered battery eliminator.
