Once again, old thread.. but a really good one for sure.

But reading all of this and researching in many different places on bias and how to implement it I'm left with a resounding question: Why isn't at least some sort of AB bias just standard equipment in all SSB capable amplifiers, even CB amps?

After all, the circuits are really never all that complex, and the cost in parts is quite low.. A decent thermally tracked bias circuit would add all of $10 in parts in the extreme case when you factor in the discounts afforded when buying in bulk plus a little extra time to build it in.. You could just have a standard bias board made in China for $5.00 or less apiece and stick one in your amp for every transistor pair..

It just seems to me such a comparatively cheap and simple thing for all the fuss that surround it.
