Yes, I do. I'd rather not hook it up to the wall outlet though, because the alarm clock was broken and I suspect it was a short in the cable I would have to use to plug it in. Which, I suspect, would be bad.
Are you certain the four wires are on the secondary. If the clock was manufactured for the "international market" it is possible that the primary comprises a pair of 120 volt windings which would be wired in series for use on 240 volts.
