A 24VA 12V at 2A chassis power supply for just £3.29 including shipping? I just had to buy one purely to test and take to bits to see if it was the deathtrap quality so common of cheap Chinese power supplies.
When it arrived I was surprised to see that it was actually quite well made and even passed a 1000V insulation test between it's mains and low voltage sides. The video shows the insides of the unit with a commentary.
Sorry for the rumbly noise picked up by the camera. I'll try to lessen that with some foam isolation pads in the future.
For those enquiring, the item reviewed can be found on ebay here:-

Do keep in mind that quality and even circuitry can vary between batches and suppliers. These cheap no-brand supplies should not be used to power items where there is a risk of people contacting even the low voltage DC side. Also note that the means of connection for the mains necessitates that these chassis supplies be mounted in a suitably ventilated enclosure.

And here lies the first official format we've come to know and love. But you're upside down! lol
Found me some vintage Big Clive. Glad you don't have those riverdancing upstairs neighbours anymore!
The Chinese are starting to build much better products.
Just so much stuff on Ebay from China so cheap! 99p upwards! Free postage! How the feck is this possible?!!!
Hello, good video.
I have this power supply and it broke when I caused a short on the DC side.
A change of the backup bracte no success. What else could be broken. Please help.
Please excuse this english. Google translator, hmmm. I am a german.
Just bought an amazon AC voltage regulator for £1.91 My meter across an incandescent says 100 to 240 V. Trying to vary an extractor fan speed doesn't work though. Perhaps not smooth enough? Can I send you one? I reckon the ScotGov should be paying you to test all this strange and dangerous stuff! Stonking!
2019??
Great video. Horrible audio! It's good you found and killed the person playing the drums in the background!
Pliss Skematic Sirr
Is meggering these a good indicator that they would not fail into a state that would electrocute a person?
What about the efficiency at various loads?
