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...

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.

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?

If its ac then why the polarised connections though?

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.

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?

https://en.wikipedia.org/wiki/DIN_co...aker_connector

European audio equipment almost always used circular 5-pin 180 degree DIN
connectors for mic and line level inputs, and line level outputs, and used
the 2-pin connector for each speaker. My Phillips cassette recorder used it,
as did my dad's B&O record deck and his cine projector (for playing sound
through external amp or for dubbing onto the soundtrack).

It was even fitted on Japanese equipment such as Sony radio-cassette
players.

It was only in the 1980s that I first saw phono plugs for line-level
connections between equipment (eg record deck, cassette deck, CD player,
graphic equalizer to amplifier). Phono plugs require more plugs (separate
for left and right) whereas DIN combines both in one plug. ON the other
hand, DIN plugs are more difficult to solder wires onto because the pins are
very close together.

I remember that a lot of equipment had three-pin speaker sockets which would
allow a two-pin plug to be plugged in either way round (ie spade connector
always in the centre hole but pin in either of the holes). I'm not sure what
the thinking was there, because as far as I could tell, the two pins were
connected together so you didn't get phase-reversal buy reversing the plug.

Yes although compared to the mini DINs I've used on the early macs they are **** easy to connect in comparision.

This was for speakers wasn't it not christmas tree lights.
I didn't use them on my speakers I used 4mm plugs.

Apparently human ears can't detect the differnt phase so it shouldn;t make a differnce.

Most wall warts come with barrel or jack connectors with some you get a choice but I've yet to see the ones you say you have a wall wart for.

,
says...

European audio equipment almost always used circular 5-pin 180 degree DIN
connectors for mic and line level inputs, and line level
outputs ....

One 5-pin plug could handle both stereo inputs and outputs
on a single connector so that tape recorder connected to a
mixer, for example, could have line level outputs for
playback and line level inputs for recording from a vatiety
of sources with one cable although it was adviseable to use
cable with four individually screened conductors to avoid
crosstalk.

A radio might be equipped with a so-called Diode connector
in which the record and playback functions were reversed so
that the same straight through cable without a crossover
could be used to connect a tape recorder and receiver
together.

The original connecors with a solid metal barrel were
excellent but the later ones with two plated half screens
punched out of thin sheet metal with the whole thing held
together by a plastic sleeve were not so good. They worked
fine but were too suscepible to damage if one dangled on the
floor and got trodden on!

The original phono plugs which were around at the time,
though, were terrible by comparison!

It was only in the 1980s that I first saw phono plugs for line-level
connections between equipment (eg record deck, cassette deck, CD player,
graphic equalizer to amplifier). Phono plugs require more plugs
(separate for left and right) whereas DIN combines both in one plug. ON
the other hand, DIN plugs are more difficult to solder wires onto
because the pins are very close together.

Just for information, the Quad II valve equipment used phono connectors.
The later generation 3 Series went over to DIN connectors - a retrograde
step IMHO, as they are nothing like so reliable long term. They have a
habit of oxidising and becoming intermittent. But do have a smaller
footprint on the rear panel.

There are much higher quality connectors made to the same pin layout by
Touchel. Which have locking rings too. Used on some microphones etc. I'd
guess the extra cost ruled them out for domestic gear.

It about the cheapest nastiest connector ever made.

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

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.

I've got a couple of wall warts - AC - that drove 12v spots. They have
standard DIN speaker connectors.

Easier to use the same connectors for all their ****.

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...

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?

complete nonsense


So what do you think it means?

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.

Nope, jacks are cheaper.

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.

You make even less sense this time, if that's possible

Delighted to have provided so much pre-Christmas entertainment, but I'm
still trying to find a replacement.
