Hey Dawg...
Find the short, don't flail around guessing and hoping you replace the right one..
Desolder the leads/ find out if the winding's shorted to the other winding...see if your load is shorted to ground...read the print!!! C'MON!!!

I personally suspect your mod transformer itself is shorted...either internally to the core or secondary winding...
IT HAPPENS!!
...especially with the low quality-made in china transformers
If you're smart you'll get the print and use your head, not yPour wallet!
