1. I've built two power amp in one casing with two separeted transformers. When I turn on both supply, it produces a loud noise and the IC become overheat. But when I disconnect one of the both supply, it back to normal condition.

2. If I use two transformer like the one I mentioned above, can I connect both 0V together?

Anyone can help this?
Thanks.
