degital PSU transformr details needed ?
i got my hands on an old degital power supply unit , the model is : koocu 1501t
it is 0-15 volt , with variable voltage and amperage
see picure http://i00.i.aliimg.com/img/pb/172/988/490/490988172_927.jpg
but unfortunately , it was not working
i opened it , it has a big transformer with one pair of wires as primary (220 v) and 3 pairs as secondery ( green - black and yellow)
search for datashhet or any details about the transformer , and found nothing
i need to know the value of the three outpots voltages so i can replace them .
thank you in advance , ad sorry for the bad english :)
