Just open any amateur radio amplifier.. and copy.
That's all they are doing anyway.
And you would be correct.
The issue I have to add with that, and many others, IMHO is in "Do you understand what you are doing?" - that is the problem.
Which I give credit to Lou Franklin, whom did make some effort in educating the masses on Why and How an Amp works, not just "What goes where - do this. Buy this here - for that..."
The problem beyond, in regards to that era, that has been the lack of consolidation of the knowledge base between CB and Amateur - which really is our current quandary - the separation of those that have and those that don't.
The ones here (us in Forums like this) are dealing with the "Great Big Empty" (Chasm) that exists because the hands that used to wash each other now don't.
I have no idea why the "Falling out" per-se - but the gap is wide - and it doesn't seem to be narrowing any time soon, even with the advent of such things like the Internet which is the repository of such information.
Why we don't see it, the information that can make amps operate correctly is beyond me to understand at this moment.
