Default qustion about amps

Hi.
Is it possible to use high frequency transformer on a class D amplifier output , and filter after transformer ?

I have tried this with TDA7480 , but it didnt work well.I connected transformer directly , it didnt work at all.After putting series resistor (with transformer) it started to operate , but the resistor (6w) was heating so much that it de-soldered !
After trying to put a capacitor at output , the TDA7480 fried out .

What is my problem ?

Thanks in advance,

Lukas
