A bit of advice:
..........a circuit without DC bias. *The Vbe max
is only 4 Volts, which gives a useful hint!
Hey OM,
I don't thin so. The hint should be the input impedence is like less
than 1 ohm. And although you may state that Vbe max is 4, that may
apply in class C but not say class AB where the all yoiu will be doing
is varying the current thru the base and the voltage will swing next
to nothing, like a base swing current of 10 or more amps into the base
impendence.
So you can't find a good schematic for a linear, I suggest you get a
good spice program, and a really big smith chart.
I wouldn't use teflon board of any kind, when teflon burns it turns to
mustard gas.
