Q: there is no way to get 420Watts from ±24V. check NXP datasheet for this TDA chip.. why supply voltage limit is 28V? chip itself withstand at least ±40V. With such supply voltage 420w is possible..

Toerfa 28 * 1.41 = 39.4 Volt after rectifying. That is near 41Volt. Besides a transformer has a little higher voltage with no load. Better be safe.
