Thanks! I will check this.
murta79:
Here are some photos of the "crater" I carved out.

Btw, even though the transformer is not smoking any more it becomes really hot after 10-15 minutes. Not sure how hot it should get since I don´t have a non-faulty instrument to measure on, but I guess it should not be hot to touch  :-\
factory:
Do you have anything to measure the temperature with? and/or a plug in mains power meter? both could be used to determine if the transformer has shorted turns.

Don´t have my power meter here at the moment, will get it tomorrow. But I just measured the temperature with a thermocouple, and it reads ~92degrees C after 5 minutes. And the even though the rate of the rise gets slower it was still going up at 5 minutes.
factory:
That seems high to me.
