The article about TDA 7294 was published along with pcb layout in Elektor few years back. Even they have published recently TDA7293 artwork which can be adapted to TDA 7294. If u can go ahead with .ps file then i can send it to u. Hope this helps u.

take a look at my thread

Question about this 7294 amp

Although I'm not an expert, this design is fairly easy to build. I suggest that you add some "security" such as a protection on the outputs to protect your loudpspeakers.

Concerning the power supply, a transformer and a diodes bridge seems to be sufficient.
If you plan to drive 8ohms speakers, the author recommends a 2X30V 150VA transformer (for 1 channel)
If you plan to drive 4ohms speakers, the author recommends a 2X24V 150VA transformer (for 1 channel)
Personally, I think these values are a bit "tight". Personally I would use a 2X24V transformer when driving 8ohms loads at the cost of a little lower output power.

Finally, I'm just a newbie with little experience. If anyone has useful tips etc., then go ahead and share with us !

Hope this helps !
