Default AC - DC adapter

If its ac then why the polarised connections though?

Anyone any thoughts on where I could get a replacement for one of these:

I've Googled but not found anything.

Christmas lights: 240v - 4v 1VA with a spade and pin plug.


The logo on the label implies it is AC output. 1VA is very low power.

Try it with 4.5v DC (3x AA cells) and a diode in series and see what
lights up. Then take a look in Maplin if you don't mind paying throught
the nose or eBay if you are not in a hurry. The PSUs that come with a
range of connector fittings are you best bet.

4.5DC might be OK if the LED chain isn't relying on AC power to work
properly. You might get away subverting an old mobile phone charger...
