Most CB amps that are biased are unregulated. Texas star being one if them. You've got the right idea with the big ceramic resistor because that's how it works. Bias current is set with the amplifier manually keyed and no drive. The hotter it gets and the harder its driven makes it drift towards class C.

The reason it's font this was is because it's a cheap and easy way to make an amplifier play well on SSB. It keeps the transistors from switching on and off between words and sounding like a class C amplifier on SSB.
