Below is a complete solution, hi-fi to be used in conjunction with those small, cheap MP3 panels. The module has 2 TDA7294 providing about 80 + 80 WRMS (maximum) on two channels and then about 160 WRMS to one mono channel (for this, closing all jumpers and using the outputs as specified BRIDGE).
The transformer of the power supply is basically the same recipe ever, but follows:
Primary - 40 turns of 26 AWG divided into 2 layers of 20 turns to the side between them;
Symmetrical secondary (amplifier) - 10 + 10 turns of 17 AWG wire (no need to spend two)
Secondary cooler - 4 turns 26AWG wire
Secondary MP3 Player (that goes to the voltage regulator) - 5 turns of 26AWG wire

Here some previews:
Here follows a video that I made with it in operation:
Módulo compacto completo para painel MP3 - YouTube
NOTE: BEFORE SOMEONE SAY THAT I JUST DO THIS TEST WITH MUSIC, LIGHT THAT WANNA LEAVE and purposeful THAT BECAUSE HOW SHE ever used BEFORE WITH OTHER AMPLIFIERS AND THEIR RESPECTIVE VIDEOS ARE POSTED, STAFF ABLE TO MAKE A COMPARISON BETWEEN THEM SONORITY EVEN THROUGH A RECORDING.
Well, as you can see by the photos and the video, a simple cooler PC processor does the trick, because the TDA are spectacular, do not heat up almost anything and have a pretty cool power within your proposal.

Renatoscp hi friend, can you share the schematics of the project please.
I need the schematics for to connect the transformer, thanks
