Ouch mate, not another one!  Hopefully you haven't damaged the one from your South Park. Smoke though, doesn't sound good, I have my fingers crossed for you.  As others have mentioned, you need to check all secondary connections/circuits for a short. Transformers don't just fail, well very very rarely anyway. Your machine has a fault and you need to find and fix it before plugging in anymore transformers.

Hate to say it and it won't make you feel any better, I did give you that advice a couple of weeks ago........

If you do find a replacement, make sure you test the circuits immediately after the transformer for shorts. You don't want to fry the replacment.

Good luck, I feel sorry for you in this situation.
