    I made this dice pyramid that I want to light from inside with
    incandescent bulbs and I bought this radio shack 12.6 volt xformer,
    but it has a "center tapped secondary" and I don't know what that
    means or how to wire it to power some 12 volt bulbs.

    can anybody help?
     
  2. You just ignore the center-tap (do not connect it). I assume you know that
    the transformer current/power rating must not be exceeded or it will get too
    hot and self-destruct!

    The secondary winding has a centre tap (a connection in the middle) so
    that between either end of the secondary and the tap you would measure
    6 volts.

    Just ignore it and wire your bulbs to the other two secondary
    connections.
