Quote from: Loudthud on October 11, 2016, 01:19:40 PMI hadn't looked at the second schematic where it says the rail Voltage is only 26V. Using that, R20 dissipates about 7W when the amp is making a square wave. That's not unreasonable for a 5W wire wound resistor. In a HiFi amp it's no problem.Is that a 4 Ohm speaker?
