Well, I usually feel a bit uneasy giving advice on things that have the potential to either kill someone or damage their equipment if they don't do it properly...
I'll give you some general info though.
I would definitely suggest you use a voltage regulator to provide a steady 12V output.
An LM7812 regulator IC would work well here, as it can handle up to an amp's worth of current, which should be plenty for your application.
You need to stay at least 1.5V above the output voltage for it to work properly, and the maximum input voltage is 35V.
The output of the transformer would be 12V
RMS which after the reservoir capacitor will be about 17V
Peak. (12*2
0.5)
Another thing to keep in mind with the LM7812 ICs is that they generate an enormous amount of heat dissipation. IME, proper heatsinking is needed at as little as 30-40mA.
