take a look at my thread :)

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 !
