I want to make one 200W @ 8ohms Class AB for 2 way active PA speaker system. I want to use another 50W@8ohms for tweeter. The amplifier must be rugged. Suggest some good circuits.
Hi,
I would go for the ESP 300W design and reduce the transformer voltage to match your power requirement.
I think it's P101 you need not the sub-bass amp; http://sound.westhost.com/projects.htm
