Default AC - DC adapter

Anyone any thoughts on where I could get a replacement for one of these:
https://www.flickr.com/gp/161457453@N02/iv5D72

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...

Do the light flash or do anything clever? the AC input might be used for
timing purposes?

OK well try the 3 x 1.5v battery route and it might work or if not, it
is not too hard to knock up a squarewave oscillator at 50hz running from
a DC supply which should bring back the twinkle to your lights.
Also worth opening up the old transformer and see if just the thermal
fuse has failed?

They used to be used for speaker connections IIRC, and few have such speakers now so they probbaly got a good deal on them from a suplier or scrap merchant

Look up 2 pin DIN, if that's what is shown in the picture.

I have seen a lot of wall warts with these connectors, and *none* have
been DIN speaker connectors (I have some of those, and I compared them).
They may look the same on a photo, but they are quite a bit bigger.

1VA is a very low rating. I'd be inclined to try a generic USB charger
and hope it didn't make the lights go bang from moderate over-voltage
or because it's DC instead of AC.

If you are worried, then get an lm317 three terminal regulator and a
suitable pot and get it just right on a charger with more volts out, like
one of those beefier usb ones.
It might get a bit warm. Seems odd to me if its AC though, as leds are most
definitely DC.

Not worth the effort for such low power. Dropping 0.6v across a cheap
silicon diode or two in series will bring a 5v supply down to 4v.

At 1W total power mostly in the LEDs any rectifier diode like 1N4001
(about 2p each) would be well within its rating 1W @ 4v = 250mA.

I like the way it says its a "safety isolating transformer" and then
tells you pin 1 is connected to the coil end.
This implies an autotransformer with a single coil and that is *not* an
isolating transformer.
When are you taking it apart to see what's actually inside?

It doesn't say what it means. I don't have mind reading powers. However the conclusion that it means the transformer is unisolated is simply nonsense.

Just as well I didn't say it wasn't isolated then.

However your assumption that it is is based on what it says even though
it contradicts itself.

That makes your assumption nonsense not mine.

Impossible to say without testing whether its actually an autotransformer or
not.

Nearest I can see is a 4.5v one from CPC: PW02731

You would have to cut the cable from the old one and graft it to the new;
those spade and pin plugs (NOT speaker plugs) are not that common.

Loads on Ebay - both line male and female. They were used on car radios

Finding an exact one with the correct plug may be difficult. If it is just
a simple power supply - and not an LED driver/sequencer - any of the
correct spec should do if you are up to fitting a matching connector(s)
