The TN 12 has three terminals 2 +ve and 1 -ve.
When used with a Yacht Boy if the radio is off using the on/off push button on the top, and the power line switched on using the switch on the TN12 cable then the dial lights come on independent of the radio.
This feed is from the central +ve terminal and the -ve terminal. The radio can then be powered powered up/down using the on/off push button and this feed comes from the outer +ve terminal and the -ve terminal.
The output of the TN12 for the radio is 9V, and as Tom_I says you can either use a TN12 or a PP9 or 6 "C" cells. However with the battery option you do not have permanently on dial lights.
