Scott -

The 107 (spokesman or orator) requires 18vac to function properly. It will work with a 2012b transformer OR with 18vac found on all 1A2 power supplies.

Connect the red wire from the 107 to terminal R on the phone's network. Connect the green wire to terminal GN on the network and connect the black and yellow wires to 18 volts AC from the power supply. If you need an external transformer, I probably have one, but why use one if you've got a working 1A2 system?
