ken,
that type circuit is typically loaded by the base emitter junctions of two transistors each with a base emitter resistor usually 10-15ohms they often have a diode to ground on the output as seen to the left of the input transformer,
it works with or without the regulator or tracking, adding the regulator stiffens load regulation a little but its not load stable,
hf sets use the regulator and tracking where most cb amps dont.

i have not used spice, i experiment and take measurements, could spice help choose more suitable components?
