The amplifier circuit is very Cheapest and cans be powered from 24 to 32 V/5A dual power supply. You must try this circuit. Its working great. Because 4 transistors (2 x 2n3055 and mj 2955) on the final amplifier will of some very hot then add the aluminum finned cooler and the fan so That the transistor is not too high temperatures
