Hello all!
I made amplifier with TDA7294 under this schematics (Figure 1-F). When you turn on this amplifier to power Ucc =+/-37V itself humming. When disconnection is powered by 1 to 2 seconds then stops playing well. Of its output is switched 80W speaker 8ohm. Please help to solve a problem ... why not amp to work?
thanks
