I do not know why the components after said toroid get excited if less than 12v is used if built for 9v….. I am basically a math guy.

Because the toroid is connected as an RF transformer, and the "small change" result in different transformer turns ratios which in turn results in different voltages being imposed upon the output FETs when power is being reflected back from the load.??
