try to do this by ur self it's better for u than to had a prepered circuit but i think that u must modifie the output stage ithink u had a transsistor in the outout stage replace it's by a powerful transistor or use the triacs i'ts more useful than transistor

You mean using SCR's not triacs as triacs conduct AC current
SCR's were used in High power units where other types of transistors were not available, because triacs need commitator capacitos to ensure turning off when changing state as flip flop specially the load is inductive, if capacitors were not correctly chosen, the SCR'c will burn out.
Now it is easy to find 200 Amps switching transistors or FETs so now Hi power FETs are widely used
