Driver300, your right it could work, but I only just got this transformer, don't really want to rip it to bits
I guessed that vandalism wasn't high on your list of priorites.
Here is a less permanent suggestion.
Firstly find the approximate volts per turn. to do that, feed the transformer with 230 V and measure the voltage on one turn. You can just feed one lead of your voltmeter through the center of the transformer, and short the probes together and that will show you the voltage.
Now devide 230 V by this and it will give you the number of turns on the primary. I expect about 1V per turn, so about 200 - 300 turns on the primary.
Now wind more turns around the transformer. If you add 10%, the output voltage will drop 10%. Just use some PVC insulated wire. It doesn't have to be neat.
You have to put the wires the right way round, so put a 60W bulb in series and check the voltage on the transformer and on the series combination of the transformer and the extra turns. The voltage on the transformer must be less than the voltage on the combination. If not, you have the extra windings the wrong way round.
Once you have the windings the correct way round, you can feed the combination directly from 230V.
Obviously, be carefull messing with 230V.
Good luck.
