Design a class - A transformer-coupled emitter-follower amplifier to deliver 10 W to an 8 Ohm speaker. The ambient temp is 25 C and the maximum junction temp is Tj max = 150 C. assume the thermal resistance value are dev-case = 3.2 C/W, case-snk = .8 C/W, and snk-amb = 4 C/W. specifiy the power supply voltage , transformer turns ratio, bias resistor values , transistor current, voltage and power rating.
